                      Statement of Additional Information
                               dated July 1, 1998
 
    Prudential Municipal Bond Fund (the Fund) is an open-end, diversified,
management investment company, or mutual fund, consisting of three separate
portfolios--the High Income Series, the Insured Series and the Intermediate
Series. The investment objectives of the Series are as follows: (i) the
objective of the High Income Series is to provide the maximum amount of income
that is eligible for exclusion from federal income taxes, (ii) the objective of
the Insured Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes consistent with the preservation of
capital and (iii) the objective of the Intermediate Series is to provide a high
level of income that is eligible for exclusion from federal income taxes
consistent with the preservation of capital. Although each Series will seek
income that is eligible for exclusion from federal income taxes, a portion of
the dividends and distributions paid by each Series (and, in particular, the
High Income Series) may be treated as a preference item for purposes of the
alternative minimum tax. Each Series seeks to achieve its objective through the
separate investment policies described under "Investment Objectives and
Policies." There can be no assurance that the Series' investment objectives will
be achieved.
 
    The Fund's address is Gateway Center Three, 100 Mulberry Street, Newark, New
Jersey 07102-4077, and its telephone number is (800) 225-1852.
 
    This Statement of Additional Information is not a prospectus and should be
read in conjunction with the Fund's Prospectus dated July 1, 1998, a copy of
which may be obtained from the Fund upon request.

                              GENERAL INFORMATION
 
    On May 3, 1995, the Trustees approved a change in the name of the Modified
Term Series to the Intermediate Series, effective June 29, 1995. On June 23,
1998, the Trustees approved a change in the name of the High Yield Series to the
High Income Series, effective July 1, 1998.
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
    Prudential Municipal Bond Fund is a diversified, open-end, management
investment company consisting of three separate portfolios: the High Income
Series, the Insured Series and the Intermediate Series. The investment
objectives of the Series are as follows: (i) the objective of the High Income
Series is to provide the maximum amount of income that is eligible for exclusion
from federal income taxes, (ii) the objective of the Insured Series is to
provide the maximum amount of income that is eligible for exclusion from federal
income taxes consistent with the preservation of capital and (iii) the objective
of the Intermediate Series is to provide a high level of income that is eligible
for exclusion from federal income taxes consistent with the preservation of
capital. There can be no assurance that any Series will achieve its objective.
Although each Series will seek income that is eligible for exclusion from
federal income taxes, a portion of the dividends and distributions paid by each
Series (and, in particular, the High Income Series) may be treated as a
preference item for purposes of the alternative minimum tax.
 
    The investment objective of each Series may not be changed without the
approval of the holders of a majority of the outstanding voting securities of
such Series. A "majority of the outstanding voting securities" of a Series, when
used in the Prospectus or this Statement of Additional Information, means the
lesser of (i) 67% of the voting shares of a Series represented at a meeting at
which more than 50% of the outstanding voting shares of a Series are present in
person or represented by proxy or (ii) more than 50% of the outstanding voting
shares of a Series.
 
    Each Series will seek to achieve its investment objective by investing in a
diversified portfolio of obligations issued by or on behalf of states,
territories and possessions of the United States and the District of Columbia
and their political subdivisions, agencies and instrumentalities, the interest
on which is eligible for exclusion from federal income taxation (municipal
obligations or municipal securities). Each Series pursues its investment
objective through the separate investment policies described below and in the
Prospectus. There can be no assurance that the Series' investment objectives
will be achieved.
 
THE HIGH INCOME SERIES
 
    The High Income Series invests primarily in municipal obligations rated B or
better by Moody's Investors Service (Moody's) or Standard & Poor's Ratings Group
(S&P) or a similar nationally recognized statistical rating organization (NRSRO)
having maturities generally in excess of ten years. The Series also will invest
in municipal obligations having maturities ranging from one year to ten years.
The weighted average maturity of the portfolio is expected to range between 15
and 30 years.
 
THE INSURED SERIES
 
    The Insured Series invests primarily in municipal obligations which are
insured, rated in the highest rating category of Moody's or S&P or a similar
NRSRO, or backed by the U.S. Government. The Series may also invest up to 5% of
its total assets in municipal obligations rated A/A or Aa/AA by Moody's or S&P,
respectively, or a similar NRSRO. It is anticipated that the Series will offer
generally lower yields and be subject to less credit and market risk than the
High Yield Series.
 
    It is anticipated that, under current market conditions, a great majority of
the municipal obligations held by the Insured Series will be insured by the
following entities: MBIA Insurance Corporation (MBIA Corp.), AMBAC Indemnity
Corporation (AMBAC), Financial Guaranty Insurance Company (FGIC) and Financial
Security Assurance Inc. (FSA). Each of these entities is described more fully
below. The Series will not invest in obligations insured by The Prudential
Insurance Company of America (Prudential), except as may be permitted by
applicable law, nor will it settle any claim under portfolio insurance provided
by an insurer whose insurance obligations are reinsured by an affiliate of
Prudential for less than full payment except in accordance with an exemptive
order obtained from the Securities and Exchange Commission (Commission).
 
    MBIA Corp. (formerly known as Municipal Bond Investors Assurance
Corporation) is the principal operating subsidiary of MBIA Inc., a New York
Stock Exchange listed company. As of December 31, 1997, MBIA Corp. had admitted
assets of approximately $5.256 billion, total liabilities of approximately
$3.496 billion and total policyholders' surplus of approximately $1.760 billion.
MBIA Inc. is not obligated to pay the debts of or claims against MBIA Corp. MBIA
Corp. is domiciled in the state of New York and licensed to do business in all
50 states, the District of Columbia, the Commonwealth of Puerto Rico, the
Commonwealth of the Northern Mariana Islands, the Virgin Islands of the United
States and the Territory of Guam. MBIA Corp. has one European branch in the
Republic of France.
 
                                      B-2
<PAGE>
    FGIC Corporation, the owner of FGIC, is a wholly-owned subsidiary of General
Electric Capital Corporation. Neither FGIC Corporation nor General Electric
Capital Corporation is obligated to pay the debts of or claims against FGIC. As
of December 31, 1997, FGIC had admitted assets of approximately $2.535 billion,
total liabilities of approximately $1.279 billion and total policyholders'
surplus of approximately $1.256 billion.
 
    AMBAC is a Wisconsin-domiciled stock insurance corporation regulated by the
Office of the Commissioner of Insurance of the State of Wisconsin and licensed
to do business in 50 states, the District of Columbia and the Commonwealth of
Puerto Rico, with admitted assets of approximately $2.842 billion, total
liabilities of approximately $1.872 billion and total policyholders' surplus of
approximately $1.00 billion as of December 31, 1997. Statutory capital consists
of AMBAC policyholders' surplus and statutory contingency reserve. AMBAC is a
wholly-owned subsidiary of AMBAC, Inc., a 100% publicly-held company.
 
    FSA is a wholly-owned subsidiary of Financial Security Assurance Holdings,
Ltd. (Holdings), a New York Stock Exchange listed company. Holdings is owned
approximately 40.4% by US West Capital Corporation (US WEST), 11.5% by Fund
American Enterprises Holdings, Inc. (Fund American), and 6.4% by The Tokio
Marine and Fire Insurance Co., Ltd. (Tokio Marine). Neither US WEST, Fund
American, Tokio Marine nor any other shareholder of Holdings is obligated to pay
the debts of or claims against FSA. As of December 31, 1997, FSA had admitted
assets of approximately $1.331 billion, total liabilities of approximately $.832
billion and total policyholders' surplus of approximately $.498 billion. The
company formerly known as Capital Guaranty Insurance Company is now a subsidiary
of FSA.
 
THE INTERMEDIATE SERIES
 
    The Intermediate Series invests primarily in municipal obligations rated Baa
or BBB or better by Moody's or S&P, respectively, or a similar nationally
recognized statistical rating organization, with maturities of 3 to 15 years and
with a dollar-weighted average portfolio maturity of more than 3 and less than
10 years. Under normal circumstances, at least 60% of the municipal obligations
purchased by the Series will be rated A or better by Moody's or S&P. It is
anticipated that this Series will offer generally lower yields and be subject to
less market risk than the High Yield Series or the Insured Series.
 
GENERAL
 
    The Prudential Investment Corporation (PIC), doing business as Prudential
Investments (PI, the Subadviser or the investment adviser), maintains a
fixed-income research group which provides credit analysis and research on
fixed-income securities. The portfolio manager consults routinely with the
research group in managing the Fund's portfolios. The fixed-income research
group, which currently maintains a staff of 26 persons including 22 credit
analysts, reviews on an ongoing basis issuers of fixed-income obligations,
including prospective purchases and portfolio holdings of the Series. Credit
analysts have broad access to research and financial reports, data retrieval
services and industry analysts. They review financial and operating statements
supplied by state and local governments and other issuers of municipal
securities to evaluate revenue projections and the financial soundness of
municipal issuers. They study the impact of economic and political developments
on state and local governments, evaluate industry sectors and meet periodically
with public officials and other representatives of state and local governments
and other tax-exempt issuers to discuss such matters as budget projections, debt
policy, the strength of the regional economy and, in the case of revenue bonds,
the demand for facilities. They also make site inspections to review specific
projects and to evaluate the progress of construction or the operation of a
facility.
 
    Each Series may invest in municipal securities which are not rated if, based
upon a credit analysis by the Subadviser, the Subadviser believes that the
securities are of comparable quality to other municipal securities that the
Series may purchase. A description of the ratings is set forth under the heading
"Description of Security Ratings" in the Fund's Prospectus. The ratings of
Moody's and S&P represent the respective opinions of those firms of the quality
of the securities each undertakes to rate. The ratings are general and are not
absolute standards of quality. In determining the suitability for investment in
a particular unrated security, the Subadviser will take into consideration asset
and debt service coverage, the purpose of the financing, the history of the
issuer, the existence of other rated securities of the issuer, any credit
enhancement by virtue of a letter of credit or other financial guaranty deemed
suitable by the investment adviser and other factors as may be relevant,
including comparability to other issuers.
 
    After its purchase by a Series of the Fund, an issue of municipal bonds or
notes may cease to be rated or its rating(s) may be reduced. Neither event
requires the elimination of that obligation from the portfolio of the Series,
but each event will be a factor in determining whether the Series should
continue to hold that issue in its portfolio.
 
                                      B-3
<PAGE>
    Each Series will attempt to invest substantially all of its net assets in
municipal securities. Under normal market conditions, each Series anticipates
that its assets will be invested so that at least 80% of its net assets will be
invested in municipal securities. Each Series will continuously monitor its
portfolio to ensure that the asset investment test is met at all times, except
for temporary defensive positions during abnormal market conditions.
 
    A Series may invest its assets from time to time on a temporary basis in
debt securities, the interest on which is subject to federal, state or local
income tax: (i) pending the investment or reinvestment in municipal securities
of the proceeds from the sale of shares of the Series or sales of portfolio
securities, (ii) in order to avoid the necessity of liquidating portfolio
investments to meet redemptions of shares by investors, or (iii) where market
conditions due to rising interest rates or other adverse factors warrant
temporary investing. Investments in taxable securities may include: obligations
of the U.S. Government, its agencies or instrumentalities; commercial paper
rated in the two highest grades by either Moody's or S&P (A-1 and A-2, or P-1
and P-2, respectively), except that the Insured Series may invest only in
commercial paper rated A-1 or P-1; certificates of deposit and bankers'
acceptances; other debt securities rated within the three highest grades by
either Moody's or S&P or, if unrated, judged by the Subadviser to possess
comparable creditworthiness; and repurchase agreements with respect to any of
the foregoing investments. Each Series does not intend to invest more than 5% of
its assets in any one category of the foregoing taxable securities. A Series may
also hold its assets in other cash equivalents or in cash.
 
    The Fund, as well as each Series of the Fund, is classified as diversified
under the Investment Company Act of 1940, as amended (the Investment Company
Act). This means that with respect to 75% of the assets of a Series, (i) the
Series may not invest more than 5% of its total assets in the securities of any
one issuer (except U.S. Government obligations) and (ii) the Series may not own
more than 10% of the outstanding voting securities of any one issuer. For
purposes of diversification and concentration under the Investment Company Act,
the identification of the issuer of the municipal obligation depends upon the
terms and conditions of the obligation. If the assets and revenues of an agency,
authority, instrumentality or other political subdivision are separate from
those of the government creating the subdivision and the obligation is backed
only by the assets and revenues of the subdivision, the subdivision is regarded
as the sole issuer. Similarly, in the case of an industrial development revenue
bond or pollution control revenue bond, if the bond is backed only by the assets
and revenues of the non-governmental user, the non-governmental user is regarded
as the sole issuer. If, in either case, the creating government or another
entity guarantees an obligation, the guaranty may be regarded as a separate
security and treated as an issue of the guarantor.
 
    Each Series will treat an investment in a municipal bond refunded with
escrowed U.S. Government securities as U.S. Government securities for purposes
of the Investment Company Act's diversification requirements provided: (i) the
escrowed securities are "government securities" as defined in the Investment
Company Act, (ii) the escrowed securities are irrevocably pledged only to
payment of debt service on the refunded bonds, except to the extent there are
amounts in excess of funds necessary for such debt service, (iii) principal and
interest on the escrowed securities will be sufficient to satisfy all scheduled
principal, interest and premiums on the refunded bonds and a verification report
prepared by a party acceptable to a nationally recognized statistical rating
agency, or counsel to the holders of the refunded bonds, so verifies, (iv) the
escrow agreement provides that the issuer of the refunded bonds grants and
assigns to the escrow agent, for the equal and ratable benefit of the holders of
the refunded bonds, an express first lien on, pledge of and perfected security
interest in the escrowed securities and the interest income thereon, (v) the
escrow agent had no lien of any type with respect to the escrowed securities for
payment of its fees and expenses except to the extent there are excess
securities, as described in (ii) above, and (vi) the Series will not invest more
than 25% of its total assets in pre-refunded bonds of the same municipal issuer.
 
    Since securities issued or guaranteed by states or municipalities are not
voting securities, there is no limitation on the percentage of a single issuer's
securities which a Series may own so long as, with respect to 75% of its assets,
it does not invest more than 5% of its total assets in the securities of that
issuer (except obligations issued or guaranteed by the U.S. Government). As for
the other 25% of the assets of a Series not subject to the limitation described
above, there is no minimum limitation as to the number of issuers in whose
securities these assets may be invested.
 
    The Fund expects that normally a Series will not invest 25% or more of its
total assets in any one sector of the municipal obligations market, including:
hospitals; nursing homes, retirement facilities and other health facilities;
turnpikes and toll roads; solid waste and resource recovery; ports and airports;
colleges, universities and other educational facilities; state and local housing
finance programs; obligations of municipal water and sewer utilities systems,
obligations of municipal electric and gas utilities systems; or other industrial
development and pollution control facilities. However, depending upon prevailing
market conditions, a Series may have 25% or more of its total assets invested in
any one sector of the municipal obligations market. Each of the foregoing types
of investments might be subject to particular risks which, to the extent that a
Series is concentrated in such investments, could affect the value or liquidity
of the Series' portfolio.
 
                                      B-4
<PAGE>
    A portion of the dividends and distributions paid on the shares of each
Series of the Fund may be treated as a preference item for purposes of the
alternate minimum tax for individuals and corporations. Such treatment may cause
certain investors, depending upon other aspects of their individual tax
situation, to incur some federal income tax liability. The Fund's Subadviser
intends (except with respect to the High Income Series) to invest in securities
so as to minimize the portion of such dividends or distributions that are
treated as a tax preference item. In addition, corporations are subject to an
alternative minimum tax which treats as a tax preference item 75% of a
corporation's adjusted current earnings. A corporation's adjusted current
earnings would include interest paid on municipal obligations and dividends paid
on shares of the Fund. See "Taxes, Dividends and Distributions."
 
    As in the past, proposals may be submitted to Congress in the future with
the intended effect of eliminating or further restricting the issuance of
municipal obligations or the federal tax exemption for interest paid on
municipal obligations. In that event, the Fund may re-evaluate its investment
objectives.
 
    Unlike many issues of common and preferred stock and corporate bonds which
are traded between brokers acting as agents for their customers on securities
exchanges, municipal obligations are customarily purchased from or sold to
dealers who are selling or buying for their own account. Most municipal
obligations are not required to be registered with or qualified for sale by
federal or state securities regulators. Since there are large numbers of
municipal obligation issues of many different issuers, most issues do not trade
on any single day. On the other hand, most issues are always marketable, since a
major dealer will normally, on request, bid for any issue, other than obscure
ones. Regional municipal securities dealers are frequently more willing to bid
on issues of municipalities in their geographic area.
 
    Although almost all municipal obligations are marketable, the structure of
the market introduces its own element of risk; a seller may find, on occasion,
that dealers are unwilling to make bids for certain issues that the seller
considers reasonable. If the seller is forced to sell, he or she may realize a
capital loss that would not have been necessary in different circumstances.
Because the net asset value of a Series' shares reflects the degree of
willingness of dealers to bid for municipal obligations, the price of a Series'
shares may be subject to greater fluctuation than shares of other investment
companies with different investment policies. See "Net Asset Value."
 
MUNICIPAL SECURITIES
 
    Municipal securities include notes and bonds issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies and instrumentalities and the District of Columbia, the
interest on which is generally eligible for exclusion from federal income tax
and, in certain instances, applicable state or local income and personal
property taxes. Such securities are traded primarily in the over-the-counter
market.
 
    MUNICIPAL BONDS. Municipal bonds are issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as airports, bridges, highways, housing, hospitals, mass transportation,
schools, streets, water and sewer works and gas and electric utilities.
Municipal bonds also may be issued in connection with the refunding of
outstanding obligations and obtaining funds to lend to other public institutions
or for general operating expenses.
 
    The two principal classifications of municipal bonds are general obligation
and revenue. General obligation bonds are secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.
Revenue bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special excise tax or other specific revenue source.
 
    Industrial development bonds (IDBs) are issued by or on behalf of public
authorities to obtain funds to provide various privately-operated facilities for
business and manufacturing, housing, sports, pollution control, and for airport,
mass transit, port and parking facilities. Although IDBs are issued by municipal
authorities, they are generally secured by the revenues derived from payments of
the industrial user. The payment of the principal and interest on IDBs is
dependent solely on the ability of the user of the facilities financed by the
bonds to meet its financial obligations and the pledge, if any, of real and
personal property so financed as security for the payment.
 
    MUNICIPAL NOTES. Municipal notes generally are used to provide for
short-term capital needs and generally have maturities of one year or less.
Municipal notes include:
 
    1.  TAX ANTICIPATION NOTES. Tax Anticipation Notes are issued to finance
working capital needs of municipalities. Generally, they are issued in
anticipation of various seasonal tax revenues, such as income, sales, use and
business taxes, and are payable from these specific future taxes.
 
    2.  REVENUE ANTICIPATION NOTES. Revenue Anticipation Notes are issued in the
expectation of reception of other kinds of revenue, such as federal revenues
available under the Federal Revenue Sharing Programs.
 
                                      B-5
<PAGE>
    3.  BOND ANTICIPATION NOTES. Bond Anticipation Notes are issued to provide
interim financing until long-term financing can be arranged. In most cases, the
long-term bonds then provide the money for the repayment of the Notes.
 
    4.  CONSTRUCTION LOAN NOTES. Construction Loan Notes are sold to provide
construction financing. Permanent financing, the proceeds of which are applied
to the payment of Construction Loan Notes, is sometimes provided by a commitment
by the Government National Mortgage Association (GNMA) to purchase the loan,
accompanied by a commitment by the Federal Housing Administration to insure
mortgage advances thereunder. In other instances, permanent financing is
provided by commitments of banks to purchase the loan.
 
    TAX-EXEMPT COMMERCIAL PAPER. Issues of tax-exempt commercial paper, the
interest on which is generally exempt from federal income taxes, typically are
represented by short-term, unsecured, negotiable promissory notes. These
obligations are issued by agencies of state and local governments to finance
seasonal working capital needs of municipalities or to provide interim
construction financing and are paid from general revenues of municipalities or
are refinanced with long-term debt. In most cases, tax-exempt commercial paper
is backed by letters of credit, lending agreements, note repurchase agreements
or other credit facility agreements offered by banks or other institutions and
is actively traded.
 
    FLOATING RATE AND VARIABLE RATE SECURITIES. Each Series may invest more than
5% of its assets in floating rate and variable rate securities, including
participation interests therein and inverse floaters. Floating or variable rate
securities often have a rate of interest that is set as a specific percentage of
a designated base rate, such as the rate on Treasury Bonds or Bills or the prime
rate at a major commercial bank. These securities also allow the holder to
demand payment of the obligation on short notice at par plus accrued interest,
which amount may be more or less than the amount the holder paid for them.
Variable rate securities provide for a specified periodic adjustment in the
interest rate. The interest rate on floating rate securities changes whenever
there is a change in the designated base interest rate. Floating rate and
variable rate securities typically have long maturities but afford the holder
the right to demand payment at earlier dates. Such floating rate and variable
rate securities will be treated as having maturities equal to the period of
adjustment of the interest rate.
 
    An inverse floater is a debt instrument with a floating or variable interest
rate that moves in the opposite direction of the interest rate on another
security or the value of an index. Changes in the interest rate on the other
security or index inversely affect the residual interest rate paid on the
inverse floater, with the result that the inverse floater's price will be
considerably more volatile than that of a fixed rate bond. The market for
inverse floaters is relatively new.
 
    LIQUIDITY PUTS. Each Series may purchase and exercise puts on municipal
bonds and notes. Puts give the Series the right to sell securities held in the
portfolio at a specified exercise price on a specified date. Puts may be
acquired to reduce the volatility of the market value of securities subject to
puts. The acquisition of a put may involve an additional cost to the Series
compared to the cost of securities with similar credit ratings, stated
maturities and interest coupons but without applicable puts. This increased cost
may be paid either by way of an initial or periodic premium for the put or by
way of a higher purchase price for securities to which the put is attached. In
addition, there is a credit risk associated with the purchase of puts in that
the issuer of the put may be unable to meet its obligation to purchase the
underlying security. Accordingly, each Series will acquire a put only under the
following circumstances: (i) the put is written by the issuer of the underlying
security and the security is rated within the quality grades in which the Series
is permitted to invest; (ii) the put is written by a person other than the
issuer of the underlying security and that person has securities outstanding
which are rated within the quality grades in which the Series is permitted to
invest; or (iii) the put is backed by a letter of credit or similar financial
guaranty issued by a person having securities outstanding which are rated within
the quality grades in which the Series is permitted to invest.
 
    Puts will be valued at an amount equal to the difference between the value
of the underlying security taking the put into consideration and the value of
the same or a comparable security without taking the put into consideration.
 
    LENDING OF SECURITIES. Consistent with applicable regulatory requirements,
each Series may lend its portfolio securities to brokers, dealers and financial
institutions, provided that outstanding loans do not exceed in the aggregate 33%
of the value of the Series' total assets and provided that such loans are
callable at any time by the Series and are at all times secured by cash or
equivalent collateral or obtains a letter of credit that is equal to at least
the market value, determined daily, of the loaned securities. The advantage of
such loans is that the Series continues to receive payments in lieu of the
interest and dividends on the loaned securities, while at the same time earning
interest either directly from the borrower or on the collateral which will be
invested in short-term obligations.
 
    A loan may be terminated by the borrower on one business day's notice or by
the Series any time. If the borrower fails to maintain the requisite amount of
collateral, the loan automatically terminates, and the Series can use the
collateral to replace the securities while holding the borrower liable for any
excess of replacement cost over collateral. As with any extensions of credit,
there are risks of delay in recovery and in some cases loss of rights in the
collateral should the borrower of the securities fail
 
                                      B-6
<PAGE>
financially. However, these loans of portfolio securities will only be made to
firms determined to be creditworthy pursuant to procedures approved by the
Fund's Trustees. On termination of the loan, the borrower is required to return
the securities to the Series, and any gain or loss in the market price during
the loan would inure to the Series.
 
    Since voting or consent rights which accompany loaned securities pass to the
borrower, the Series will follow the policy of calling the loan, in whole or in
part as may be appropriate, to permit the exercise of such rights if the matters
involved would have a material effect on the Series' investment in the
securities which are the subject of the loan. The Series will pay reasonable
finders', administrative and custodial fees in connection with a loan of its
securities or may share the interest earned on collateral with the borrower.
 
    FUTURES CONTRACTS. Each Series may engage in transactions in financial
futures contracts as a hedge against interest rate related fluctuations in the
value of securities which are held in the investment portfolio or which the
Series intends to purchase. A clearing corporation associated with the
commodities exchange on which a futures contract trades assumes responsibility
for the completion of transactions and guarantees that open futures contracts
will be closed. Although interest rate futures contracts call for actual
delivery or acceptance of debt securities, in most cases the contracts are
closed out before the settlement date without the making or taking of delivery.
 
    When the futures contract is entered into, each party deposits in a
segregated account approximately 5% of the contract amount, called the initial
margin. Subsequent payments to and from the broker, called variation margin,
will be made on a daily basis as the price of the underlying security or index
fluctuates, making the long and short positions in the futures contracts more or
less valuable, a process known as "marking to market." In the case of options on
futures contracts, the holder of the option pays a premium and receives the
right, upon exercise of the option at a specified price during the option
period, to assume a position in the futures contract (a long position if the
option is a call and a short position if the option is a put). If the option is
exercised by the holder before the last trading day during the option period,
the option writer delivers the futures position, as well as any balance in the
writer's futures margin account. If it is exercised on the last trading day, the
option writer delivers to the option holder cash in an amount equal to the
difference between the option exercise price and the closing level of the
relevant index on the date the option expires.
 
    When a Series purchases a futures contract, it will maintain an amount of
cash or other liquid assets in a segregated account so that the amount so
segregated plus the amount of initial and variation margin held in the account
of its broker equals the market value of the futures contract, thereby ensuring
that the use of such futures contract is unleveraged. A Series that has sold a
futures contract may cover that position by owning the instruments underlying
the futures contract or by holding a call option on such futures contract. A
Series will not sell futures contracts if the value of such futures contracts
exceeds the total market value of the securities of the Series. It is not
anticipated that transactions in futures contracts will have the effect of
increasing portfolio turnover.
 
    OPTIONS ON FINANCIAL FUTURES. Each Series may purchase call options and
write put and call options on futures contracts and enter into closing
transactions with respect to such options to terminate an existing position.
Each Series will use options on futures in connection with hedging strategies.
 
    An option on a futures contract gives the purchaser the right, in return for
the premium paid, to assume a position in a futures contract (a long position if
the option is a call and a short position if the option is a put) at a specified
exercise price at any time during the period of the option. Upon exercise of the
option, the delivery of the futures position by the writer of the option to the
holder of the option will be accompanied by delivery of the accumulated balance
in the writer's futures margin account which represents the amount by which the
market price of the futures contract, at exercise, exceeds, in the case of a
call, or is less than, in the case of a put, the exercise price of the option on
the futures contract. If an option is exercised on the last trading day prior to
the expiration date of the option, the settlement will be made entirely in cash
equal to the difference between the exercise price of the option and the closing
price of the futures contract on the expiration date. Currently options can be
purchased or written with respect to futures contracts on U.S. Treasury Bonds,
among other fixed-income securities, and on municipal bond indices on the
Chicago Board of Trade. As with options on debt securities, the holder or writer
of an option may terminate his or her position by selling or purchasing an
option of the same series. There is no guaranty that such closing transactions
can be effected.
 
    When a Series hedges its portfolio by purchasing a put option, or writing a
call option, on a futures contract, it will own a long futures position or an
amount of debt securities corresponding to the open option position. When a
Series writes a put option on a futures contract, it may, rather than establish
a segregated account, sell the futures contract underlying the put option or
purchase a similar put option.
 
    LIMITATIONS ON PURCHASE AND SALE. Under regulations of the Commodity
Exchange Act, investment companies registered under the Investment Company Act
are exempted from the definition of commodity pool operator, subject to
compliance with
 
                                      B-7
<PAGE>
certain conditions. The exemption is conditioned upon a Series' purchasing and
selling futures contracts and options thereon for BONA FIDE hedging
transactions, except that a Series may purchase and sell futures contracts and
options thereon for any other purpose, to the extent that the aggregate initial
margin and option premiums do not exceed 5% of the liquidation value of the
Series' total assets. Each Series will use financial futures in a manner
consistent with these requirements. Each Series will continue to invest at least
80% of its net assets in municipal bonds and municipal notes except in certain
circumstances, as described in the Prospectus under "How the Fund
Invests--Investment Objectives and Policies." A Series may not enter into
futures contracts if, immediately thereafter, the sum of the amount of initial
and net cumulative variation margin on outstanding futures contracts, together
with premiums paid on options thereon, would exceed 20% of the total assets of
the Series.
 
    RISKS OF FINANCIAL FUTURES TRANSACTIONS. In addition to the risk associated
with predicting movements in the direction of interest rates, discussed in "How
the Fund Invests--Hedging Strategies--Futures Contracts and Options Thereon" in
the Prospectus, there are a number of other risks associated with the use of
financial futures for hedging purposes.
 
    Each Series intends to purchase and sell futures contracts only on exchanges
where there appears to be a market in the futures sufficiently active to
accommodate the volume of its trading activity. There can be no assurance that a
liquid market will always exist for any particular contract at any particular
time. Accordingly, there can be no assurance that it will always be possible to
close a futures position when such closing is desired; and, in the event of
adverse price movements, the Series would continue to be required to make daily
cash payments of variation margin. However, if futures contracts have been sold
to hedge portfolio securities, these securities will not be sold until the
offsetting futures contracts can be purchased. Similarly, if futures have been
bought to hedge anticipated securities purchases, the purchases will not be
executed until the offsetting futures contracts can be sold.
 
    The hours of trading of interest rate futures contracts may not conform to
the hours during which the Series may trade municipal securities. To the extent
that the futures markets close before the municipal securities market,
significant price and rate movements can take place that cannot be reflected in
the futures markets on a day-to-day basis.
 
    RISKS OF TRANSACTIONS IN OPTIONS ON FINANCIAL FUTURES. In addition to the
risks which apply to all options transactions, there are several special risks
relating to options on futures. The ability to establish and close out positions
on such options will be subject to the maintenance of a liquid secondary market.
Compared to the sale of financial futures, the purchase of put options on
financial futures involves less potential risk to a Series because the maximum
amount at risk is the premium paid for the options (plus transaction costs).
However, there may be circumstances when the purchase of a put option on a
financial future would result in a loss to a Series when the sale of a financial
future would not, such as when there is no movement in the price of debt
securities.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although a Series generally
will purchase only those options for which there appears to be an active
secondary market, there is no assurance that a liquid secondary market on an
exchange will exist for any particular option, or at any particular time, and
for some options, no secondary market on an exchange may exist. In such event,
it might not be possible to effect closing transactions in particular options
with the result that a Series would have to exercise its options in order to
realize any profit and would incur transaction costs upon the sale of underlying
securities pursuant to the exercise of put options.
 
    Reasons for the absence of a liquid secondary market on an exchange include
the following: (i) there may be insufficient trading interest in certain
options; (ii) restrictions may be imposed by an exchange on opening transactions
or closing transactions or both; (iii) trading halts, suspensions or other
restrictions may be imposed with respect to particular classes or series of
options or underlying securities; (iv) unusual or unforeseen circumstances may
interrupt normal operations on an exchange; (v) the facilities of an exchange
may not at all times be adequate to handle current trading volume; or (vi) one
or more exchanges could, for economic or other reasons, decide or be compelled
at some future date to discontinue the trading of options (or a particular class
or series of options), in which event the secondary market on that exchange (or
in that class or series of options) would cease to exist, although outstanding
options on that exchange could continue to be exercisable in accordance with
their terms.
 
    There is no assurance that higher than anticipated trading activity or other
unforeseen events might not, at times, render certain clearing facilities
inadequate, and thereby result in the institution by an exchange of special
procedures which may interfere with the timely execution of customers' orders.
 
REPURCHASE AGREEMENTS
 
    The Fund's repurchase agreements will be collateralized by U.S. Government
obligations. The Fund will enter into repurchase transactions only with parties
meeting creditworthiness standards approved by the Fund's Trustees. The Fund's
investment
 
                                      B-8
<PAGE>
adviser will monitor the creditworthiness of such parties, under the general
supervision of the Trustees. In the event of a default or bankruptcy by a
seller, the Fund will promptly seek to liquidate the collateral. To the extent
that the proceeds from any sale of such collateral upon a default in the
obligation to repurchase are less than the repurchase price, the Fund will
suffer a loss.
 
    The Fund participates in a joint repurchase account with other investment
companies managed by Prudential Investments Fund Management LLC (PIFM) pursuant
to an order of the Commission. On a daily basis, any uninvested cash balances of
the Fund may be aggregated with those of such investment companies and invested
in one or more repurchase agreements. Each fund participates in the income
earned or accrued in the joint account based on the percentage of its
investment.
 
PORTFOLIO TURNOVER
 
    A Series may engage in short-term trading consistent with its investment
objective. Portfolio transactions will be undertaken in response to anticipated
movements in the general level of interest rates. Municipal securities or
futures contracts may be sold in anticipation of a market decline (resulting
from a rise in interest rates) or purchased in anticipation of a market rise
(resulting from a decline in interest rates) and later sold. In addition, a
security may be sold and another purchased at approximately the same time to
take advantage of what the investment adviser believes to be a temporary
disparity in the normal yield relationship between the two securities. Yield
disparities may occur for reasons not directly related to the investment quality
of particular issues or the general movement of interest rates, due to factors
such as changes in the overall demand for or supply of various types of
municipal securities or changes in the investment objectives of investors.
 
    Except as described above and under "Investment Restrictions," the foregoing
investment policies are not fundamental and may be changed by the Trustees of
the Fund without the vote of a majority of its outstanding voting securities.
 
SEGREGATED ACCOUNTS
 
    When the Fund is required to segregate assets in connection with certain
hedging transactions, it will maintain cash or other liquid assets in a
segregated account. "Liquid assets" means cash, U.S. Government securities,
foreign securities, equity securities, debt obligations or other liquid,
unencumbered assets marked-to-market daily.
 
                            INVESTMENT RESTRICTIONS
 
    The following restrictions are fundamental policies. Fundamental policies
are those which cannot be changed without the approval of the holders of a
majority of a Series' outstanding voting securities. A "majority of the
outstanding voting securities" of a Series, when used in this Statement of
Additional Information, means the lesser of (i) 67% of the voting shares
represented at a meeting at which more than 50% of the outstanding voting shares
are present in person or represented by proxy or (ii) more than 50% of the
outstanding voting shares.
 
    Each Series may not:
 
     1. Purchase securities on margin (but the Series may obtain such short-term
credits as may be necessary for the clearance of transactions and for margin
payments in connection with transactions in financial futures contracts and
options thereon).
 
     2. Make short sales of securities or maintain a short position.
 
     3. Issue senior securities, borrow money or pledge its assets, except that
each Series may borrow up to 33 1/3% of the value of its total assets
(calculated when the loan is made) for temporary, extraordinary or emergency
purposes and to take advantage of investment opportunities or for the clearance
of transactions. The Series may pledge up to 33 1/3% of the value of its total
assets to secure such borrowings. For purposes of this restriction, the
preference as to shares of a Series in liquidation and as to dividends over all
other Series of the Fund with respect to assets specifically allocated to that
Series, the purchase or sale of securities on a when-issued or delayed delivery
basis, the purchase and sale of financial futures contracts and collateral
arrangements with respect thereto and obligations of the Series to Trustees,
pursuant to deferred compensation arrangements, are not deemed to be the
issuance of a senior security or a pledge of assets.
 
     4. Purchase any security if as a result, with respect to 75% of the total
assets of the Series, more than 5% of the total assets of the Series would be
invested in the securities of any one issuer (provided that this restriction
shall not apply to obligations issued or guaranteed as to principal and interest
by the U.S. Government or its agencies or instrumentalities).
 
     5. Purchase securities (other than municipal obligations and obligations
guaranteed as to principal and interest by the U.S. Government or its agencies
or instrumentalities) if, as a result of such purchase, 25% or more of the total
assets of the Series
 
                                      B-9
<PAGE>
(taken at current market value) would be invested in any one industry. (For
purposes of this restriction, industrial development bonds, where the payment of
the principal and interest is the ultimate responsibility of companies within
the same industry, are grouped together as an "industry.")
 
     6. Buy or sell commodities or commodity contracts, except financial futures
contracts and options thereon.
 
     7. Buy or sell real estate or interests in real estate, although it may
purchase and sell securities which are secured by real estate and securities of
companies which invest or deal in real estate.
 
     8. Act as underwriter except to the extent that, in connection with the
disposition of portfolio securities, it may be deemed to be an underwriter under
certain federal securities laws.
 
     9. Purchase securities of other investment companies, except in the open
market involving only customary brokerage commissions and as a result of which
no more than 10% of its total assets (determined at the time of investment)
would be invested in such securities or except in connection with a merger,
consolidation, reorganization or acquisition of assets.
 
    10. Invest in interests in oil, gas or other mineral exploration or
development programs.
 
    11. Make loans, except through repurchase agreements and loans of portfolio
securities (limited to 33% of the Series' total assets).
 
    12. Purchase or write puts, calls or combinations thereof except as
described in the Prospectus and this Statement of Additional Information with
respect to puts and options on futures contracts.
 
    13. Invest for the purpose of exercising control or management of another
company.
 
    Whenever any fundamental investment policy or investment restriction states
a maximum percentage of a Series' assets, it is intended that if the percentage
limitation is met at the time the investment is made, a later change in
percentage resulting from changing total or net asset values will not be
considered a violation of such policy. However, in the event that a Series'
asset coverage for borrowings falls below 300%, the Series will take prompt
action to reduce its borrowings, as required by applicable law.

    The officers conduct and supervise the daily business operations of the
Fund, while the Trustees, in addition to their functions set forth under
"Manager" and "Distributor," review such actions and decide on general policy.
 
    The Trustees have adopted a retirement policy which calls for the retirement
of Trustees on December 31 of the year in which they reach the age of 72, except
that retirement is being phased in for Trustees who were age 68 or older as of
December 31, 1993. Under this phase-in provision, Messrs. Beach, Dorsey, Jacobs
and O'Brien are scheduled to retire on December 31, 1999, 1999, 1998 and 1999,
respectively.
 
    Pursuant to the terms of the Management Agreement with the Fund, the Manager
pays all compensation of officers and employees of the Fund as well as the fees
and expenses of Trustees of the Fund who are affiliated persons of the Manager.
The Fund pays each of its Trustees who is not an affiliated person of PIFM or
Prudential Investments annual compensation of $5,500, in addition to certain
out-of-pocket expenses. The amount of annual compensation paid to each Director
may change as a result of the introduction of additional funds upon which the
Director will be asked to serve.
 
    Trustees may receive their Trustees' fees pursuant to a deferred fee
agreement with the Fund. Under the terms of the agreement, the Fund accrues
daily the amount of such Trustee's fees which accrue interest at a rate
equivalent to the prevailing rate applicable to 90-day U.S. Treasury Bills at
the beginning of each calendar quarter or, pursuant to an SEC exemptive order,
at the daily rate of return of the Fund. Payment of the interest so accrued is
also deferred and accruals become payable at the option of the Trustee. The
Fund's obligation to make payments of deferred Trustees' fees, together with
interest thereon, is a general obligation of the Fund.
 
    Pursuant to the Management Agreement with the Fund, the Manager pays all
compensation of officers and employees of the Fund as well as the fees and
expenses of all Trustees of the Fund who are affiliated persons of the Manager.

                                    MANAGER
 
    The manager of the Fund is Prudential Investments Fund Management LLC (PIFM
or the Manager), Gateway Center Three, Newark, 100 Mulberry Street, New Jersey
07102-4077. The Manager serves as manager to all of the other open-end
management investment companies that, together with the Fund, comprise the
Prudential Mutual Funds. See "How the Fund is Managed--Manager" in the
Prospectus. As of May 31, 1998, PIFM managed and/or administered open-end and
closed-end management investment companies with assets of approximately $66.5
billion and, according to the Investment Company Institute, as of December,
1997, the Prudential Mutual Funds were the 18th largest family of mutual funds
in the United States.
 
    The Manager is a subsidiary of Prudential Securities and Prudential.
Prudential Mutual Fund Services LLC (the Transfer Agent), a wholly owned
subsidiary of the Manager, serves as the transfer agent for the Prudential
Mutual Funds and, in addition, provides customer service, recordkeeping and
management and administration services to qualified plans.
 
    Pursuant to the Management Agreement with the Fund (the Management
Agreement), the Manager, subject to the supervision of the Fund's Trustees and
in conformity with the stated policies of the Fund, manages both the investment
operations of each Series and the composition of each Series' portfolio,
including the purchase, retention, disposition and loan of securities. In
connection therewith, the Manager is obligated to keep certain books and records
of the Fund. The Manager also administers the Fund's business affairs and, in
connection therewith, furnishes the Fund with office facilities, together with
those ordinary clerical and bookkeeping services which are not being furnished
by State Street Bank and Trust Company, the Fund's custodian, and the Fund's
transfer and dividend disbursing agent. The services of the Manager for the Fund
are not exclusive under the terms of the Management Agreement and the Manager is
free to, and does, render management services to others.
 
    For its services, the Manager receives, pursuant to the Management
Agreement, a fee at an annual rate of .50 of 1% of the average daily net assets
of each Series up to $1 billion and .45 of 1% of the average daily net assets in
excess of $1 billion. PIFM has agreed to waive 10% of its management fee
(approximately .05 of 1% of average net assets, as annualized) with respect to
the
 
                                      B-14
<PAGE>
High Income Series. The fee is computed daily and payable monthly. The
Management Agreement also provides that, in the event the expenses of the Fund
(including the fees of the Manager, but excluding interest, taxes, brokerage
commissions, distribution fees and litigation and indemnification expenses and
other extraordinary expenses not incurred in the ordinary course of the Fund's
business) for any fiscal year exceed the lowest applicable annual expense
limitation established and enforced pursuant to the statutes or regulations of
any jurisdiction in which the Fund's shares are qualified for offer and sale,
the compensation due the Manager will be reduced by the amount of such excess.
Reductions in excess of the total compensation payable to the Manager will be
paid by the Manager to the Fund. No such reductions were required during the
fiscal year ended April 30, 1998. No jurisdiction currently limits the Fund's
expenses.
 
    In connection with its management of the business affairs of the Fund, the
Manager bears the following expenses:
 
    (a) the salaries and expenses of all of its and the Fund's personnel except
the fees and expenses of Trustees who are not affiliated persons of the Manager
or the Subadviser;
 
    (b) all expenses incurred by the Manager or by the Fund in connection with
managing the ordinary course of the Fund's business, other than those assumed by
the Fund as described below; and
 
    (c) the costs and expenses payable to the Subadviser pursuant to the
subadvisory agreement between the Manager and the Subadviser (the Subadvisory
Agreement).
 
    Under the terms of the Management Agreement, the Fund is responsible for the
payment of the following expenses: (a) the fees payable to the Manager, (b) the
fees and expenses of Trustees who are not affiliated persons of the Manager or
the Subadviser, (c) the fees and certain expenses of the Custodian and Transfer
Agent, including the cost of providing records to the Manager in connection with
its obligation of maintaining required records of the Fund and of pricing the
Fund's shares, (d) the charges and expenses of legal counsel and independent
accountants for the Fund, (e) brokerage commissions and any issue or transfer
taxes chargeable to the Fund in connection with its securities transactions, (f)
all taxes and corporate fees payable by the Fund to governmental agencies, (g)
the fees of any trade associations of which the Fund may be a member, (h) the
cost of share certificates representing shares of the Fund, (i) the cost of
fidelity and liability insurance, (j) certain organization expenses of the Fund
and the fees and expenses involved in registering and maintaining registration
of the Fund and of its shares with the Commission, and the states under state
securities laws, including the preparation and printing of the Fund's
registration statements and prospectuses for such purposes and paying the fees
and expenses of notice filings made in accordance with state securities laws,
(k) allocable communications expenses with respect to investor services and all
expenses of shareholders' and Trustees' meetings and of preparing, printing and
mailing reports, proxy statements and prospectuses to shareholders in the amount
necessary for distribution to the shareholders, (l) litigation and
indemnification expenses and other extraordinary expenses not incurred in the
ordinary course of the Fund's business and (m) distribution fees.
 
    The Management Agreement provides that the Manager will not be liable for
any error of judgment or for any loss suffered by the Fund in connection with
the matters to which the Management Agreement relates, except a loss resulting
from willful misfeasance, bad faith, gross negligence or reckless disregard of
duty. The Management Agreement provides that it will terminate automatically if
assigned, and that it may be terminated without penalty by either party upon not
more than 60 days' nor less than 30 days' written notice. The Management
Agreement will continue in effect for a period of more than two years from the
date of execution only so long as such continuance is specifically approved at
least annually in conformity with the Investment Company Act. The Management
Agreement was last approved by the Trustees of the Fund, including a majority of
the Trustees who are not parties to such contract or interested persons of such
parties as defined in the Investment Company Act, on May 12, 1998 and by the
shareholders of each Series on February 19, 1988.
 
    For the fiscal year ended April 30, 1998, the Manager received a management
fee of $4,787,451 (net of waiver of $535,931), $2,384,469 (net of waiver of
$85,444) and $200,622 (net of waiver of $7,346) on behalf of the High Income
Series, Insured Series and Intermediate Series, respectively. For the fiscal
year ended April 30, 1997, PIFM received a management fee of $4,614,964 (net of
waiver of $514,371), $2,494,083 (net of waiver of $277,120) and $220,036 (net of
waiver of $24,449) on behalf of the High Income Series, Insured Series and
Intermediate Series, respectively. For the fiscal year ended April 30, 1996,
PIFM received a management fee of $4,774,952 (net of waiver of $534,026),
$2,824,806 (net of waiver of $313,867) and $265,175 (net of waiver of $29,464)
on behalf of the High Income Series, Insured Series and Intermediate Series,
respectively.
 
    The Manager has entered into a Subadvisory Agreement with the Subadviser, a
wholly-owned subsidiary of Prudential. The Subadvisory Agreement provides that
the Subadviser will furnish investment advisory services in connection with the
management of the Fund. In connection therewith, the Subadviser is obligated to
keep certain books and records of the Fund. The Manager continues to have
responsibility for all investment advisory services pursuant to the Management
Agreement and supervises the Subadviser's performance of such services. The
Subadviser is reimbursed by the Manager for the reasonable costs and expenses
incurred by the Subadviser in furnishing those services.

    Peter J. Allegrini oversees the municipal bond team at PIC. The portfolio
manager analyzes the risks and negotiates credit terms for high yield municipal
bonds to build a well-diversified portfolio of bonds that, in his opinion, have
low prices and good potential to appreciate. Then, the portfolio manager and a
credit team monitor each issuer's ability to pay interest and principal on a
timely basis, under various economic conditions. The portfolio manager seeks to
avoid making short-term gains based on interest rate movements and will shift
maturities to capture good relative returns.
 
    The Subadvisory Agreement was last approved by the Trustees, including a
majority of the Trustees who are not parties to the contract or interested
persons of any such party as defined in the Investment Company Act, on May 12,
1998, and by the shareholders of each Series on February 19, 1988.
 
    The Subadvisory Agreement provides that it will terminate in the event of
its assignment (as defined in the Investment Company Act) or upon the
termination of the Management Agreement. The Subadvisory Agreement may be
terminated by the Fund, the Manager or the Subadviser upon not more than 60
days', nor less than 30 days', written notice. The Subadvisory Agreement
provides that it will continue in effect for a period of more than two years
from its execution only so long as such continuance is specifically approved at
least annually in accordance with the requirements of the Investment Company
Act.
 
                                  DISTRIBUTOR
 
    Prudential Investment Management Services LLC (the Distributor) Gateway
Center Three, 100 Mulberry Street, Newark, New Jersey 07102-4077, acts as the
distributor of the shares of the Fund. Prior to July 1, 1998, Prudential
Securities Incorporated, One Seaport Plaza, New York, New York 10292, served as
the distributor of the shares of the Fund.
 
    Pursuant to separate Distribution and Service Plans (the Class A Plan, the
Class B Plan and the Class C Plan, collectively, the Plans) adopted by the Fund
under Rule 12b-1 under the Investment Company Act and a distribution agreement
(the Distribution Agreement), the Distributor incurs the expenses of
distributing the Fund's Class A, Class B and Class C shares. The Distributor
incurs the expenses of distributing the Fund's Class Z shares under the
Distribution Agreement, none of which are reimbursed or paid for by the Fund.
See "How the Fund is Managed--Distributor" in the Prospectus.
 
    Prior to January 22, 1990, the Fund offered only one class of shares (the
existing Class B shares). On October 11, 1989, the Trustees, including a
majority of the Trustees who are not interested persons of the Fund and who have
no direct or indirect financial interest in the operation of the Class A or
Class B Plan or in any agreement related to either Plan (the Rule 12b-1
Trustees), at a meeting called for the purpose of voting on each Plan, adopted a
new plan of distribution for the Class A shares of the Fund (the Class A Plan)
and approved an amended and restated plan of distribution with respect to the
Class B shares of the Fund (the Class B Plan). On February 9, 1993, the
Trustees, including a majority of the Rule 12b-1 Trustees, at a meeting called
for the purpose of voting on each Plan, approved the continuance of the Plans
and Distribution Agreements and approved modifications of the Fund's Class A and
Class B Plans and Distribution Agreements to conform them with recent amendments
to the National Association of Securities Dealers, Inc. (NASD) maximum sales
charge rule described below. As so modified, the Class A Plan provides that (i)
up to .25 of 1% of the average daily net assets of the Class A shares may be
used to pay for personal service and the maintenance of shareholder accounts
(service fee) and (ii) total distribution fees (including the service fee of .25
of 1%) may not exceed .30 of 1%. As so modified, the Class B Plan provides that
(i) up to .25 of 1% of the average daily net assets of the Class B shares may be
paid as a service fee and (ii) up to .50 of 1% (including the service fee) of
the average daily net assets of the Class B shares (asset-based sales charge)
may be used as reimbursement for distribution-related expenses with respect to
the Class B shares. On May 4, 1993, the Trustees, including a majority of the
Rule 12b-1Trustees, at a meeting called for the purpose of voting on each Plan,
adopted a plan of distribution for the Class C shares of the Fund and approved
further amendments to the plans of distribution for the Fund's Class A and Class
B shares changing them from reimbursement type plans to compensation type plans.
 
    Prior to July 10, 1998, Prudential Securities Incorporated (Prudential
Securities) acted as the distributor of the shares of the Fund. On May 12, 1998,
the Trustees including a majority of the Rule 12b-1 Trustees at a meeting called
for the purpose of voting on each Plan and the Distribution Agreement, adopted a
new distribution agreement and an amendment to the Class A, Class B and Class C
Plans, effective July 1,1998, under which the responsibility for distribution
was transferred from Prudential Securities to the Distributor. The Class A Plan,
as previously amended, was approved by the Class A and Class B shareholders of
each Series of the Fund and the Class B Plan, as amended, was approved by the
Class B shareholders of each Series on July 19, 1994. The Class C Plan was
approved by the sole shareholder of Class C shares of each Series on August 1,
1994.

    The Distributor also receives the proceeds of contingent deferred sales
charges paid by shareholders upon certain redemptions of Class C shares. See
"Shareholder Guide--How to Sell Your Shares--Contingent Deferred Sales Charges"
in the Prospectus. For the fiscal year ended April 30, 1998, Prudential
Securities, as the predecessor distributor, received approximately $11,600 and
$600 on behalf of the High Income Series and Intermediate Series, respectively,
in contingent deferred sales charges attributable to Class C shares and did not
receive any contingent deferred sales charges with respect to the Insured
Series.
 
    The Class A, Class B and Class C Plans continue in effect from year to year,
provided that each such continuance is approved at least annually by a vote of
the Trustees, including a majority vote of the Rule 12b-1 Trustees, cast in
person at a meeting called for the purpose of voting on such continuance. The
Plans may each be terminated at any time, without penalty, by the vote of a
majority of the Rule 12b-1 Trustees or by the vote of the holders of a majority
of the outstanding shares of the applicable class on not more than 30 days'
written notice to any other party to the Plans. The Plans may not be amended to
increase materially the amounts to be spent for the services described therein
without approval by the shareholders of the applicable class (by both Class A
and Class B shareholders, voting separately, in the case of material amendments
to the Class A Plan) and all material
 
                                      B-17
<PAGE>
amendments are required to be approved by the Trustees in the manner described
above. Each Plan will automatically terminate in the event of its assignment.
The Fund will not be contractually obligated to pay expenses incurred under any
Plan if it is terminated or not continued.
 
    Pursuant to each Plan, the Trustees will review at least quarterly a written
report of the distribution expenses incurred on behalf of each class of shares
of the Fund by the Distributor. The report will include an itemization of the
distribution expenses and the purposes of such expenditures. In addition, as
long as the Plans remain in effect, the selection and nomination of Rule 12b-1
Trustees shall be committed to the Rule 12b-1 Trustees.
 
    Pursuant to the Distribution Agreement, the Fund has agreed to indemnify the
Distributor to the extent permitted by applicable law against certain
liabilities under federal securities laws. The Distribution Agreement was
approved by the Trustees, including a majority of the Rule 12b-1 Trustees, on
May 12, 1998.
 
    NASD MAXIMUM SALES CHARGE RULE. Pursuant to rules of the NASD, the
Distributor is required to limit aggregate initial sales charges, deferred sales
charges and asset-based sales charges to 6.25% of total gross sales of each
class of shares. Interest charges on unreimbursed distribution expenses equal to
the prime rate plus one percent per annum may be added to the 6.25% limitation.
Sales from the reinvestment of dividends and distributions are not included in
the calculation of the 6.25% limitation. The annual asset-based sales charge on
shares of a Series may not exceed .75 of 1% per class. The 6.25% limitation
applies to each class of each Series of the Fund rather than on a per
shareholder basis. If aggregate sales charges were to exceed 6.25% of total
gross sales of any class, all sales charges on shares of that class would be
suspended.
 
                      PORTFOLIO TRANSACTIONS AND BROKERAGE
 
    The Manager is responsible for decisions to buy and sell securities and
financial futures for each Series of the Fund, the selection of brokers, dealers
and futures commission merchants to effect the transactions and the negotiation
of brokerage commissions, if any. The term "Manager" as used in this section
includes the Subadviser. Purchases and sales of securities on a securities
exchange, which are not expected to be a significant portion of the portfolio
securities of any Series, are effected through brokers who charge a commission
for their services. Orders may be directed to any broker or futures commission
merchant including, to the extent and in the manner permitted by applicable law,
the Distributor and its affiliates. Brokerage commissions on United States
securities, options and futures exchanges or boards of trade are subject to
negotiation between the Manager and the broker or futures commission merchant.
 
    In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own accounts without a stated
commission, although the price of the security usually includes a profit to the
dealer. In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid. The Fund will not deal with the Distributor
or an affiliate in any transaction in which the Distributor or an affiliate acts
as principal. Thus it will not deal in over-the-counter securities with the
Distributor or an affiliate acting as a market-maker, and it will not execute a
negotiated trade with the Distributor or an affiliate if the execution involves
the Distributor or an affiliate acting as principal with respect to any part of
the Fund's order.
 
    In placing orders for portfolio securities for the Fund, the Manager is
required to give primary consideration to obtaining the most favorable price and
efficient execution. Within the framework of this policy, the Manager will
consider the research and investment services provided by brokers, dealers or
futures commission merchants who effect or are parties to portfolio transactions
of the Fund, the Manager or the Manager's other clients. These research and
investment services are those which brokerage houses customarily provide to
institutional investors and include statistical and economic data and research
reports on particular companies and industries. These services are used by the
Manager in connection with all of its investment activities, and some of these
services obtained in connection with the execution of transactions for the Fund
may be used in managing other investment accounts. Conversely, brokers, dealers
or futures commission merchants furnishing these services may be selected for
the execution of transactions of these other accounts, whose aggregate assets
may be far larger than the Fund, and the services furnished by the brokers,
dealers or futures commission merchants may be used by the Manager in providing
investment management for the Fund. Commission rates are established pursuant to
negotiations with the broker, dealer or futures commission merchant based on the
quality and quantity of execution services provided by the broker in the light
of generally prevailing rates. The policy of the Manager is to pay higher
commissions to brokers, other than the Distributor or an affiliate, for
particular transactions than might be charged if a different broker had been
selected, on occasions when, in the Manager's opinion, this policy furthers the
objective of obtaining best price and execution. In addition, the Manager is
authorized to pay higher commissions on brokerage transactions for the Fund to
brokers other than the Distributor or an affiliate in order to secure research
and investment services described above, subject to review by the Fund's
Trustees from time to time as to the extent and
 
                                      B-18
<PAGE>
continuation of this practice. The allocation of orders among brokers and the
commission rates paid are reviewed periodically by the Fund's Trustees.
Portfolio securities may not be purchased from any underwriting or selling
syndicate of which the Distributor (or any affiliate), during the existence of
the syndicate, is a principal underwriter (as defined in the Investment Company
Act), except in accordance with rules of the Commission. This limitation, in the
opinion of the Fund, will not significantly affect the Series ability to pursue
their present investment objectives. However, in the future in other
circumstances, the Series may be at a disadvantage because of this limitation in
comparison to other funds with similar objectives but not subject to such
limitations.
 
    Subject to the above considerations, the Distributor or an affiliate may act
as a securities broker or futures commission merchant for the Fund. In order for
the Distributor or an affiliate to effect any portfolio transactions for the
Fund, the commissions, fees or other remuneration received by the Distributor or
an affiliate must not exceed certain rates set forth in the Investment Company
Act and must be reasonable and fair compared to the commissions, fees or other
remuneration paid to other brokers or futures commission merchants in connection
with comparable transactions involving similar securities or futures being
purchased or sold on an exchange during a comparable period of time. This
standard would allow the Distributor or an affiliate to receive no more than the
remuneration which would be expected to be received by an unaffiliated broker or
futures commission merchant in a commensurate arm's-length transaction.
Furthermore, the Trustees of the Fund, including a majority of the
non-interested Trustees, have adopted procedures which are reasonably designed
to provide that any commissions, fees or other remuneration paid to the
Distributor or an affiliate are consistent with the foregoing standard. In
accordance with Section 11(a) of the Securities Exchange Act of 1934, the
Distributor or an affiliate may not retain compensation for effecting
transactions on a national securities exchange for the Fund unless the Fund has
expressly authorized the retention of such compensation. The Distributor and its
affiliates must furnish to the Fund at least annually a statement setting forth
the total amount of all compensation retained by the Distributor and its
affiliates from transactions effected for the Fund during the applicable period.
Brokerage and futures transactions with the Distributor or an affiliate are also
subject to such fiduciary standards as may be imposed upon the Distributor (or
such affiliate) by applicable law.
 
    During the fiscal years ended April 30, 1998, 1997 and 1996 the Fund paid
$136,400, $163,500 and $263,800, respectively, in brokerage commissions on
certain options and/or futures transactions. No such brokerage commissions were
paid to the Distributor or any affiliate thereof.
 
                     PURCHASE AND REDEMPTION OF FUND SHARES
 
    Shares of each Series of the Fund may be purchased at a price equal to the
next determined net asset value per share (NAV) plus a sales charge which, at
the election of the investor, may be imposed either (i) at the time of purchase
(Class A shares) or (ii) on a deferred basis (Class B or Class C shares). Class
Z shares of the Fund are offered to a limited group of investors at NAV without
any sales charges. See "Shareholder Guide--How to Buy Shares of the Fund" in the
Prospectus.
 
    Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except that (i) each class is
subject to different sales charges and distribution and/or service fees (except
for Class Z shares, which are not subject to any sales charges and distribution
and/or service fees), which may affect performance, (ii) each class has
exclusive voting rights with respect to any matter submitted to shareholders
that relates solely to its arrangement and has separate voting rights on any
matter submitted to shareholders in which the interests of one class differ from
the interests of any other class, (iii) each class has a different exchange
privilege, (iv) only Class B shares have a conversion feature and (v) Class Z
shares are offered exclusively for sale to a limited group of investors. See
"Distributor" and "Shareholder Investment Account--Exchange Privilege."
 
ISSUANCE OF FUND SHARES FOR SECURITIES
 
    Transactions involving the issuance of Fund shares for securities (rather
than cash) will be limited to (i) reorganizations, (ii) statutory mergers, or
(iii) other acquisitions of portfolio securities that: (a) meet the investment
objectives and policies of the Fund, (b) are liquid and not subject to
restrictions on resale, (c) have a value that is readily ascertainable via
listing on or trading in a recognized United States or international exchange or
market, and (d) are approved by the Fund's investment adviser.

    Under the current distribution arrangements between the Fund and the
Distributor, Class A shares are sold at a maximum sales charge of 3% and Class
B* Class C* and Class Z shares are sold at NAV. Using the Fund's NAV at April
30, 1998, the maximum offering price of the Fund's shares is as follows:

   Shares--Contingent Deferred Sales Charges" in the Prospectus.
 
REDUCTION AND WAIVER OF INITIAL SALES CHARGES--CLASS A SHARES
 
    COMBINED PURCHASE AND CUMULATIVE PURCHASE PRIVILEGE. If an investor or
eligible group of related investors purchases Class A shares of the Fund
concurrently with Class A shares of other series of the Fund or other Prudential
Mutual Funds, the purchases may be combined to take advantage of the reduced
sales charge applicable to larger purchases. See the table of breakpoints under
"Shareholder Guide--Alternative Purchase Plan" in the Prospectus.
 
    An eligible group of related Fund investors includes any combination of the
following:
 
    (a) an individual;
 
    (b) the individual's spouse, their children and their parents;
 
    (c) the individual's and spouse's Individual Retirement Account (IRA);
 
    (d) any company controlled by the individual (a person, entity or group that
holds 25% or more of the outstanding voting securities of a corporation will be
deemed to control the corporation, and a partnership will be deemed to be
controlled by each of its general partners);
 
    (e) a trust created by the individual, the beneficiaries of which are the
individual, his or her spouse, parents or children;
 
    (f)  a Uniform Gifts to Minors Act/Uniform Transfers to Minors Act account
created by the individual or the individual's spouse; and
 
    (g) one or more employee benefit plans of a company controlled by an
individual.
 
    In addition, an eligible group of related Fund investors may include an
employer (or group of related employers) and one or more retirement or group
plans of such employer or employers (an employer controlling, controlled by or
under common control with another employer is deemed related to that employer).
 
    The Transfer Agent, the Distributor or your Dealer must be notified at the
time of purchase that the investor is entitled to a reduced sales charge. The
reduced sales charges will be granted subject to confirmation of the investor's
holdings. The Combined Purchase and Cumulative Purchase Privilege does not apply
to individual participants in any retirement or group plans.
 
    RIGHTS OF ACCUMULATION. Reduced sales charges are also available through
Rights of Accumulation, under which an investor or an eligible group of related
investors, as described above under "Combined Purchase and Cumulative Purchase
Privilege," may aggregate the value of their existing holdings of shares of the
Fund and shares of other Prudential Mutual Funds (excluding money market funds
other than those acquired pursuant to the exchange privilege) to determine the
reduced sales charge. However, the value of shares held directly with the
Transfer Agent and through the Distributor or a Dealer will not be aggregated to
determine the reduced sales charge. All shares must be held either directly with
the Transfer Agent or through the Distributor or a Dealer. The
 
                                      B-20
<PAGE>
value of existing holdings for purposes of determining the reduced sales charge
is calculated using the maximum offering price (net asset value plus maximum
sales charge) as of the previous business day. See "How the Fund Values its
Shares" in the Prospectus.
 
    The Distributor or the Transfer Agent must be notified at the time of
purchase that the shareholder is entitled to a reduced sales charge. The reduced
sales charges will be granted subject to confirmation of the investors'
holdings. Rights of accumulation are not available to individual participants in
any retirement or group plans.
 
    LETTER OF INTENT. Reduced sales charges are available to investors (or an
eligible group of related investors) who enter into a written Letter of Intent
providing for the purchase, within a thirteen-month period, of shares of a
Series of the Fund and shares of other Prudential Mutual Funds (Investment
Letter of Intent). Retirement and group plans may also qualify to purchase Class
A shares at NAV by entering into a Letter of Intent whereby they agree to enroll
within a thirteen-month period, a specified number of eligible employees or
participants (Participant Letter of Intent).
 
    For purposes of the Investment Letter of Intent, all shares of the Fund and
shares of other Prudential Mutual Funds (excluding money market funds other than
those acquired pursuant to the exchange privilege) which were previously
purchased and are still owned are also included in determining the applicable
reduction. However, the value of shares held directly with the Transfer Agent
and through the Distributor or a Dealer will not be aggregated to determine the
reduced sales charge.
 
    A Letter of Intent permits a purchaser, in the case of an Investment Letter
of Intent, to establish a total investment goal to be achieved by any number of
investments over a thirteen-month period and, in the case of a Participant
Letter of Intent, to establish a minimum eligible employee or participant
enrollment goal over a thirteen-month period. Each investment made during the
period, in the case of an Investment Letter of Intent, will receive the reduced
sales charge applicable to the amount represented by the goal, as if it were a
single investment. In the case of a Participant Letter of Intent, each
investment made during the period will be made at net asset value. Escrowed
Class A shares totaling 5% of the dollar amount of the Letter of Intent will be
held by the Transfer Agent in the name of the purchaser. The effective date of
an Investment Letter of Intent (except in the case of retirement and group
plans) may be back-dated up to 90 days, in order that any investments made
during this 90-day period, valued at the purchaser's cost, can be applied to the
fulfillment of the Letter of Intent goal.
 
    The Investment Letter of Intent does not obligate the investor to purchase,
nor the Fund to sell, the indicated amount. Similarly, the Participant Letter of
Intent does not obligate the retirement or group plan to enroll the indicated
number of eligible employees or participants. In the event the Letter of Intent
goal is not achieved within the thirteen-month period, the purchaser (or the
employer or plan sponsor in the case of any retirement or group plan) is
required to pay the difference between the sales charge otherwise applicable to
the purchases made during this period and the sales charge actually paid. Such
payment may be made directly to the Distributor or, if not paid, the Distributor
will liquidate sufficient escrowed shares to obtain such difference. Investors
electing to purchase Class A shares of the Fund pursuant to a Letter of Intent
should carefully read such Letter of Intent.
 
    The Distributor must be notified at the time of purchase that the investor
is entitled to a reduced sales charge. The reduced sales charge will, in the
case of an Investment Letter of Intent, be granted subject to confirmation of
the investor's holdings or, in the case of a Participant Letter of Intent,
subject to confirmation of the number of eligible employees or participants in
the retirement or group plan. Letters of Intent are not available to individual
participants in any retirement or group plans.
 
WAIVER OF THE CONTINGENT DEFERRED SALES CHARGE--CLASS B SHARES
 
    The contingent deferred sales charge (CDSC) is waived under circumstances
described in the Prospectus. See "Shareholder Guide--How to Sell Your
Shares--Waiver of Contingent Deferred Sales Charges--Class B Shares" in the
Prospectus. In connection with these waivers, the Transfer Agent will require
you to submit the supporting documentation set forth below.

QUANTITY DISCOUNT--CLASS B SHARES PURCHASED PRIOR TO AUGUST 1, 1994
 
    The CDSC is reduced on redemptions of Class B shares of the Fund purchased
prior to August 1, 1994 if immediately after a purchase of such shares, the
aggregate cost of all Class B shares of a Series of the Fund owned by you in a
single account exceeded $500,000. For example, if you purchased $100,000 of
Class B shares of the Fund and the following year purchased an additional
$450,000 of Class B shares with the result that the aggregate cost of your Class
B shares of the Fund following the second purchase was $550,000, the quantity
discount would be available for the second purchase of $450,000 but not for the
first purchase of $100,000. The quantity discount will be imposed at the
following rates depending on whether the aggregate value exceeded $500,000 or $1
million:

    You must notify the Fund's Transfer Agent either directly or through the
Distributor, Prudential Securities, Prusec, or your Dealer, at the time of
redemption, that you are entitled to the reduced CDSC. The reduced CDSC will be
granted subject to confirmation of your holdings.
 
                         SHAREHOLDER INVESTMENT ACCOUNT
 
    Upon the initial purchase of Fund shares, a Shareholder Investment Account
is established for each investor under which the shares are held for the
investor by the Transfer Agent. If a share certificate is desired, it must be
requested in writing for each transaction. Certificates are issued only for full
shares and may be redeposited in the Account at any time. There is no charge to
the investor for issuance of a certificate. The Fund makes available to its
shareholders the following privileges and plans.
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS
 
    For the convenience of investors, all dividends and distributions are
automatically reinvested in full and fractional shares of the Fund. An investor
may direct the Transfer Agent in writing not less than five full business days
prior to the record date to have subsequent dividends and/or distributions sent
in cash rather than reinvested. In the case of recently purchased shares for
which registration instructions have not been received on the record date, cash
payment will be made directly to the Dealer. Any shareholder who receives a cash
payment representing a dividend or distribution may reinvest such dividend or
distribution at NAV by returning the check or the proceeds to the Transfer Agent
within 30 days after the payment date. Such investment will be made at the NAV
next determined after receipt of the check or proceeds by the Transfer Agent.
Such shareholder will receive credit for any CDSC paid in connection with the
amount of proceeds being reinvested.
 
EXCHANGE PRIVILEGE
 
    The Fund makes available to its shareholders the privilege of exchanging
their shares of the Fund for shares of certain other Prudential Mutual Funds,
including one or more specified money market funds, subject in each case to the
minimum investment requirements of such funds. Shares of such other Prudential
Mutual Funds may also be exchanged for shares of the Fund. All exchanges are
made on the basis of the relative NAV next determined after receipt of an order
in proper form. An exchange will be treated as a redemption and purchase for tax
purposes. Shares may be exchanged for shares of another fund only if shares of
such fund may legally be sold under applicable state laws.
 
    It is contemplated that the exchange privilege may be applicable to new
mutual funds whose shares may be distributed by the Distributor.
 
    CLASS A. Shareholders of the Fund may exchange their Class A shares for
Class A shares of certain other Prudential Mutual Funds, shares of Prudential
Government Securities Trust (Short-Intermediate Term Series) and shares of the
money market funds specified below. No fee or sales load will be imposed upon
the exchange. Shareholders of money market funds who acquired such shares upon
exchange of Class A shares may use the exchange privilege only to acquire Class
A shares of the Prudential Mutual Funds participating in the exchange privilege.
 
                                      B-22
<PAGE>
    The following money market funds participate in the Class A exchange
privilege:
 
       Prudential California Municipal Fund
         (California Money Market Series)
       Prudential Government Securities Trust
         (Money Market Series)(Class A shares)
         (U.S. Treasury Money Market Series)(Class A shares)
       Prudential Municipal Series Fund
         (Connecticut Money Market Series)
         (Massachusetts Money Market Series)
         (New Jersey Money Market Series)
         (New York Money Market Series)
       Prudential MoneyMart Assets, Inc. (Class A shares)
       Prudential Tax-Free Money Fund, Inc.
 
    CLASS B AND CLASS C. Shareholders of the Fund may exchange their Class B and
Class C shares for Class B and Class C shares, respectively, of certain other
Prudential Mutual Funds and shares of Prudential Special Money Market Fund,
Inc., a money market fund. No CDSC will be payable upon such exchange, but a
CDSC may be payable upon the redemption of the Class B and Class C shares
acquired as a result of the exchange. The applicable sales charge will be that
imposed by the fund in which shares were initially purchased and the purchase
date will be deemed to be the first day of the month after the initial purchase,
rather than the date of the exchange.
 
    Class B and Class C shares of the Fund may also be exchanged for shares of
Prudential Special Money Market Fund, Inc. without imposition of any CDSC at the
time of exchange. Upon subsequent redemption from such money market fund or
after re-exchange into the Fund, such shares will be subject to the CDSC
calculated by excluding the time such shares were held in the money market fund.
In order to minimize the period of time in which shares are subject to a CDSC,
shares exchanged out of the money market fund will be exchanged on the basis of
their remaining holding periods, with the longest remaining holding periods
being transferred first. In measuring the time period shares are held in a money
market fund and "tolled" for purposes of calculating the CDSC holding period,
exchanges are deemed to have been made on the last day of the month. Thus, if
shares are exchanged into the Fund from a money market fund during the month
(and are held in the Fund at the end of the month), the entire month will be
included in the CDSC holding period. Conversely, if shares are exchanged into a
money market fund prior to the last day of the month (and are held in the money
market fund on the last day of the month), the entire month will be excluded
from the CDSC holding period. For purposes of calculating the seven year holding
period applicable to the Class B conversion feature, the time period during
which Class B shares were held in a money market fund will be excluded.
 
    At any time after acquiring shares of other funds participating in the Class
B or Class C Exchange Privilege, a shareholder may again exchange those shares
(and any reinvested dividends and distributions) for Class B or Class C shares
of the Fund, respectively, without subjecting such shares to any CDSC. Shares of
any fund participating in the Class B or Class C exchange privilege that were
acquired through reinvestment of dividends or distributions may be exchanged for
Class B or Class C shares, respectively, of other funds without being subject to
any CDSC.
 
    CLASS Z Class Z shares may be exchanged for Class Z shares of other
Prudential Mutual Funds.
 
    Additional details about the exchange privilege and prospectuses for each of
the Prudential Mutual Funds are available from the Transfer Agent, the
Distributor or your Dealer. The exchange privilege may be modified, terminated
or suspended on sixty days' notice and any fund, including the Fund, or the
Distributor, has the right to reject any exchange application relating to such
fund's shares.
 
DOLLAR COST AVERAGING
 
    Dollar cost averaging is a method of accumulating shares by investing a
fixed amount of dollars in shares at set intervals. An investor buys more shares
when the price is low and fewer shares when the price is high. The average cost
per share is lower than it would be if a constant number of shares were bought
at set intervals.
 
    Dollar cost averaging may be used, for example, to plan for retirement, to
save for a major expenditure, such as the purchase of a home, or to finance a
college education. The cost of a year's education at a four-year college today
averages around $14,000

at a private college and around $6,000 at a public university. Assuming these
costs increase at a rate of 7% a year, as has been projected, for the freshman
class beginning in 2011, the cost of four years at a private college could reach
$210,000 and over $90,000 at a public university.(1)

</TABLE>
 
AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP)
 
    Under ASAP, an investor may arrange to have a fixed amount automatically
invested in shares of a Series of the Fund monthly by authorizing his or her
bank account or Prudential Securities account (including a Command Account) to
be debited to invest specified dollar amounts in shares of the Fund. The
investor's bank must be a member of the Automatic Clearing House System. Share
certificates are not issued to ASAP participants.
 
    Further information about this program and an application form can be
obtained from the Transfer Agent, the Distributor or your Dealer.
 
SYSTEMATIC WITHDRAWAL PLAN
 
    A systematic withdrawal plan is available to shareholders through the
Transfer Agent, the Distributor or your Dealer. Such withdrawal plan provides
for monthly or quarterly checks in any amount, except as provided below, up to
the value of the shares in the shareholder's account. Withdrawals of Class B or
Class C shares may be subject to a CDSC. See "Shareholder Guide--How to Sell
Your Shares--Contingent Deferred Sales Charges" in the Prospectus.
 
    In the case of shares held through the Transfer Agent (i) a $10,000 minimum
account value applies, (ii) withdrawals may not be for less than $100 and (iii)
the shareholder must elect to have all dividends and/or distributions
automatically reinvested in additional full and fractional shares at NAV on
shares held under this plan. See "Automatic Reinvestment of Dividends and/or
Distributions" above.
 
    The Distributor and the Transfer Agent act as agents for the shareholder in
redeeming sufficient full and fractional shares to provide the amount of the
periodic withdrawal payment. The systematic withdrawal plan may be terminated at
any time, and the Distributor reserves the right to initiate a fee of up to $5
per withdrawal, upon 30 days' written notice to the shareholder.
 
    Withdrawal payments should not be considered as dividends, yield or income.
If periodic withdrawals continuously exceed reinvested dividends and
distributions, the shareholder's original investment will be correspondingly
reduced and ultimately exhausted.
 
    Furthermore, each withdrawal constitutes a redemption of shares, and any
gain or loss realized must be recognized for federal income tax purposes. In
addition, withdrawals made concurrently with purchases of additional shares are
inadvisable because of the sales charge applicable to (i) the purchase of Class
A shares and (ii) the withdrawal of Class B and Class C shares. Each shareholder
should consult his or her own tax adviser with regard to the tax consequences of
the systematic withdrawal plan, particularly if used in connection with a
retirement plan.

MUTUAL FUND PROGRAM
 
    From time to time, the Fund may be included in a mutual fund program with
other Prudential Mutual Funds. Under such a program, a group of portfolios will
be selected and thereafter marketed collectively. Typically, these programs are
marketed with an investment theme, E.G., to seek greater diversification,
protection from interest rate movements or access to different management
styles. In the event such a program is instituted, there may be a minimum
investment requirement for the program as a whole. The Fund may waive or reduce
the minimum initial investment requirements in connection with such a program.
 
    The mutual funds in the program may be purchased individually or as a part
of a program. Since the allocation of portfolios included in the program may not
be appropriate for all investors, investors should consult their Prudential
Securities Financial Adviser, Prudential/Pruco Securities Representative, or
other Dealer concerning the appropriate blends of portfolios for them. If
investors elect to purchase the individual mutual funds that constitute the
program in an investment ratio different from that offered by the program, the
standard minimum investment requirements for the individual mutual funds will
apply.
 
                                NET ASSET VALUE
 
    The NAV is the net worth of a Series (assets, including securities at value,
minus liabilities) divided by the number of shares outstanding. NAV is
calculated separately for each class. Under the Investment Company Act, the
Trustees are responsible for determining in good faith the fair value of
securities of each Series of the Fund. The Trustees have fixed the specific time
of day for the computation of each Series' NAV to be at 4:15 P.M., New York
time. In the event the New York Stock Exchange closes early on any business day,
the NAV of the Series' shares shall be determined at a time between such closing
and 4:15 P.M., New York time.
 
    Portfolio securities for which market quotations are readily available are
valued at their bid quotations. Futures contracts are valued daily at 4:15 P.M.,
New York time, at market quotations provided by the Chicago Board of Trade.
Under the Investment Company Act, the Trustees are responsible for determining
in good faith the fair value of securities and other assets of the Fund for
which market quotations are not readily available. Securities for which market
quotations are not readily available are valued at fair value in accordance with
procedures adopted by the Trustees. Under these procedures, the Manager values
municipal securities on the basis of valuations provided by a pricing service
which uses information with respect to transactions in securities, quotations
from bond dealers, market transactions in comparable securities and various
relationships between securities in determining value. This service is furnished
by Kenny-S&P, a division of J.J. Kenny Information Systems. Reliable market
quotations generally are not readily available for purposes of valuing municipal
securities. As a result, depending on the particular municipal securities owned
by the Fund, it is likely that most of the valuations for such securities will
be based upon fair value determined under the foregoing procedures. Short-term
investments are valued at amortized cost if their original term to maturity was
less than 60 days, or by amortizing their value on the 61st day prior to
maturity if their original term to maturity when acquired by the Fund was more
than 60 days, unless this valuation is determined not to represent fair value by
the Trustees.
 
    NAV is calculated separately for each class. As long as long as the Series
declare dividends daily, the NAV of the Class A, Class B, Class C and Class Z
shares will generally be the same. Series' dividends will differ by
approximately the amount any distribution and/or service fee expense accrual
differential among the classes.
 
                       TAXES, DIVIDENDS AND DISTRIBUTIONS
 
    Each Series of the Fund has elected to qualify and intends to remain
qualified to be treated as a regulated investment company under Subchapter M of
the Internal Revenue Code. In general, such election relieves each Series (but
not its shareholders) from paying federal income tax on income which is
distributed to shareholders, and permits net capital gains of the Series (I.E.,
the excess of net capital gains from the sale of assets held for more than 12
months over net short-term capital losses) to be treated as long-term capital
gains of the shareholders, regardless of how long shares in the Series are held.
 
    Subchapter M permits the character of tax-exempt interest distributed by a
regulated investment company to flow through as tax-exempt interest to its
shareholders provided that 50% or more of the value of its assets at the end of
each quarter of its taxable year is invested in state, municipal or other
obligations the interest on which is exempt for federal income tax purposes.
Distributions to shareholders of tax-exempt interest earned by any Series of the
Fund for the taxable year are generally not subject to federal income tax (see
the discussion of the alternative minimum tax below). Distributions of taxable
net investment income (including market discount on municipal obligations) and
of the excess of net short-term capital gain over net long-term capital loss are
taxable to shareholders as ordinary income.
 
    The federal alternative minimum tax may affect corporations and other
shareholders in the Fund. Interest on certain categories of tax-exempt
obligations (I.E., most private activity bonds issued after August 7, 1986) will
constitute a preference item for purposes of the alternative minimum tax. Each
Series has invested in such obligations and, therefore, receives interest
 
                                      B-25
<PAGE>
that will be treated as a preference item. Preference items received by a Series
will be allocated between the Series and its shareholders. It is possible that a
Series will incur some liability under the alternative minimum tax to the extent
preference items are allocated to it. Corporate shareholders in any of the
Series will also have to take into account interest on all municipal obligations
for purposes of the adjustment for current earnings for alternative minimum tax
purposes.
 
    The alternative minimum tax is a tax equal to 20% of a corporation's
so-called alternative minimum taxable income and 26% of a non-corporate
taxpayer's so-called alternative minimum taxable income up to $175,000 and 28%
of such income in excess of $175,000. Individual taxpayers may reduce their
alternative minimum taxable income by a standard exemption amount of $45,000
($33,750 if filing singly), although the exemption amount is reduced for
taxpayers with adjusted gross incomes of more than $150,000 ($112,500 if filing
singly). Alternative minimum taxable income is determined by adding to the
taxpayer's regularly-computed taxable income items of tax preference and certain
other adjustments. All shareholders should consult their tax advisers to
determine whether their investment in the Fund will cause them to incur
liability for the alternative minimum tax.
 
    Qualification as a regulated investment company requires, among other
things, that (a) at least 90% of the annual gross income of each Series (without
reduction for losses from the sale or other disposition of securities) be
derived from interest, dividends, payments with respect to securities loans and
gains from the sale or other disposition of securities or options thereof or
foreign currencies, or other income (including but not limited to gains from
options, futures, or forward contracts) derived with respect to its business of
investing in such securities or currencies; (b) each Series diversify its
holdings so that, at the end of each quarter of the taxable year, (i) at least
50% of the value of the assets of the Series is represented by cash, U.S.
Government securities and other securities limited in respect of any one issuer
to an amount not greater than 5% of the market value of the assets of the Series
and 10% of the outstanding voting securities of the issuer, and (ii) not more
than 25% of the value of the assets of the Series is invested in the securities
of any one issuer (other than U.S. Government securities); and (c) each Series
distribute to its shareholders at least 90% of each of (i) its net tax-exempt
interest income and (ii) its net investment income and net short-term gains
(I.E., the excess of net short-term capital gains over net long-term capital
losses) in each year.
 
    Qualification as a regulated investment company will be determined at the
level of each Series and not at the level of the Fund. Accordingly, the
determination of whether any particular Series qualifies as a regulated
investment company will be based on the activities of that Series, including the
purchases and sales of securities and the income received and expenses incurred
in that Series. Net capital gains of a Series which are available for
distribution to shareholders will be computed by taking into account any capital
loss carryforward of the Series.
 
    The High Income Series has a net capital loss carryforward as of April 30,
1998 of approximately $17,547,000 of which $2,024,000 expires in 2002,
$5,361,000 expires 2003, $6,383,000 expires in 2004, and $3,225,000 expires in
2005, and $554,000 expires in 2006. No capital gains distribution is expected to
be paid to shareholders until net gains have been realized in excess of the
aggregate of such amounts. In addition, the High Income Series elected to treat
net realized capital losses of approximately $6,709,700 incurred in the year
ended April 30, 1998, as having been incurred in the following year.
 
    Each Series may purchase debt securities (such as zero coupon bonds) that
contain original issue discount. Original issue discount that accrues in a
taxable year is treated as income earned by the Series and therefore is subject
to the distribution requirements of the Internal Revenue Code. Because the
original issue discount income earned by the Series in a taxable year may not be
represented by cash income, the Series may have to dispose of other securities
and use the proceeds to make distributions to satisfy the Internal Revenue
Code's distribution requirements.
 
    Special rules will apply to futures contracts and options thereon in which
the Series invest. See "Investment Objectives and Policies." These investments
will generally constitute "Section 1256 contracts" and will be required to be
"marked to market" for federal income tax purposes at the end of each Series'
taxable year; that is, treated as having been sold at market value. Sixty
percent of any gain or loss recognized on such "deemed sales" and on actual
dispositions will be treated as long-term capital gain or loss, and the
remainder will be treated as short-term capital gain or loss.
 
    Distributions of net capital gains are taxable to shareholders as long-term
capital gains, regardless of the length of time the shares of the Series have
been held by the shareholders.
 
    If any net capital gains are retained by a Series for investment, requiring
federal income taxes to be paid thereon by the Series, the Series will elect to
treat these capital gains as having been distributed to shareholders. As a
result, these amounts will be taxed to shareholders as capital gains, and
shareholders will be able to claim their proportionate share of the federal
income taxes paid by the Series on the gains as a credit against their own
federal income tax liabilities and will be entitled to increase the adjusted tax
basis of their shares in that Series by the difference between their PRO RATA
share of such gains and their tax credit.
 
                                      B-26
<PAGE>
    Distributions of taxable net investment income and net capital gains will be
taxable as described above, whether made in shares or in cash. Shareholders
electing to receive distributions in the form of additional shares will have a
cost basis for federal income tax purposes in each share so received equal to
the NAV of a share of the applicable Series of the Fund on the distribution
date.
 
    Any loss realized on a sale, redemption or exchange of shares of the Fund by
a shareholder will be disallowed to the extent the shares are replaced within a
61-day period (beginning 30 days before the disposition of shares). Shares
purchased pursuant to the reinvestment of a dividend will constitute a
replacement of shares.
 
    Any short-term capital loss realized upon the sale or redemption of shares
within six months (or such shorter period as may be established by Treasury
regulations) from the date of purchase of such shares and following receipt of
an exempt-interest dividend will be disallowed to the extent of such tax-exempt
dividend. Any loss realized upon the redemption of shares within 6 months from
the date of purchase of the shares and following receipt of a capital gain
distribution from the sale of assets held more than 12 months will be treated as
long-term capital loss to the extent of the capital gain distribution.
 
    Interest on indebtedness and other expenses incurred by shareholders to
purchase or carry shares of the Fund will generally not be deductible for
federal income tax purposes under Section 265 of the Internal Revenue Code. In
addition, under rules used by the Internal Revenue Service for determining when
borrowed funds are considered to be used for the purpose of purchasing or
carrying particular assets, the purchase of shares may be considered to have
been made with borrowed funds even though the borrowed funds are not directly
traceable to the purchase of shares.
 
    Persons holding certain municipal obligations who are also substantial users
(or persons related thereto) of facilities financed by such obligations may not
exclude interest on such obligations from their gross income. No investigation
as to the users of the facilities financed by municipal obligations in the
portfolios of the Series has been made by the Fund. Potential investors should
consult their tax advisers with respect to this matter before purchasing shares
of the Fund.
 
    From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on certain state and municipal obligations. It can be expected that
similar proposals may be introduced in the future. If such a proposal were
enacted, the availability of state or municipal obligations for investment by
each Series of the Fund and the value of portfolio securities held by the Series
would be affected. In addition, each Series of the Fund would reevaluate its
investment objective and policies.
 
    All distributions of taxable net investment income and net capital gains,
whether received in shares or cash, must be reported by each shareholder on his
or her federal income tax return. In addition, each shareholder must disclose on
his or her return the amount of tax-exempt dividends received from the Fund.
Under federal income tax law, each Series of the Fund will be required to report
to the Internal Revenue Service all distributions of taxable income and capital
gains as well as gross proceeds from the redemption or exchange of shares of
such Series, except in the case of certain exempt shareholders. Further, all
such distributions and proceeds from the redemption or exchange of shares may be
subject to withholding of federal income tax at the rate of 31% in the case of
nonexempt shareholders who fail to furnish the appropriate Series of the Fund
with their taxpayer identification numbers on IRS Form W-9 and with required
certifications regarding their status under the federal income tax law. If the
withholding provisions are applicable, any such distributions and proceeds,
whether taken in cash or reinvested in shares, will be reduced by the amounts
required to be withheld. Investors may wish to consult their tax advisers about
the applicability of the backup withholding provisions.
 
    Each Series is required under the Internal Revenue Code to distribute 98% of
its ordinary income in the same calendar year in which it is earned. Each Series
is also required to distribute during the calendar year 98% of the capital gain
net income it earned during the twelve months ending on October 31 of such
calendar year. In addition, the Series must distribute during the calendar year
any undistributed ordinary income and undistributed capital gain net income from
the prior year or the 12 month period ending on October 31 of such prior
calendar year, respectively. To the extent it does not meet these distribution
requirements, a Series will be subject to a non-deductible 4% excise tax on the
undistributed amount. For purposes of this excise tax, income on which the
Series pays income tax is treated as distributed.
 
    A shareholder who acquires shares of the Fund and sells or otherwise
disposes of such shares within 90 days of acquisition may not be allowed to
include certain sales charges incurred in acquiring such shares for purposes of
calculating gain or loss realized upon a sale or exchange of shares of the Fund.
 
    Dividends of net investment income and distributions of net short-term
capital gains paid to a shareholder (including a shareholder acting as a nominee
or fiduciary) who is a nonresident alien individual, a foreign corporation or a
foreign partnership (foreign shareholder) are subject to a 30% (or lower treaty
rate) withholding tax upon the gross amount of the dividends unless the
 
                                      B-27
<PAGE>
dividends are effectively connected with a U.S. trade or business conducted by
the foreign shareholder. Capital gain dividends paid to a foreign shareholder
are generally not subject to withholding tax. A foreign shareholder will,
however, be required to pay U.S. income tax on any dividends and capital gain
distributions which are effectively connected with a U.S. trade or business of
the foreign shareholder.
 
    The per share dividends on Class B and Class C shares will be lower than the
per share dividends on Class A shares as a result of the higher
distribution-related fee applicable to the Class B and Class C shares. The per
share distributions of net capital gains, if any, will be paid in the same
amount for each Class of shares. The per share dividends on Class A shares will
be lower than the per share dividends on Class Z shares, since Class Z shares
bear no distribution-related fee.
 
                            PERFORMANCE INFORMATION
 
    YIELD. Each Series may from time to time advertise its yield as calculated
over a 30-day period. Yield is calculated separately for Class A, Class B, Class
C and Class Z shares. This yield will be computed by dividing a Series' net
investment income per share earned during this 30-day period by the maximum
offering price per share on the last day of this period. Yield is calculated
according to the following formula:
 
                            a - b
               YIELD = 2[( -------   +1)to the power of 6 - 1]
                             cd
 
Where: a = dividends and interest earned during the period.
       b = expenses accrued for the period.
       c = the average daily number of shares outstanding during the
          period that were entitled to receive dividends.
       d = the maximum offering price per share on the last day of the period.
 
    Yield fluctuates and an annualized yield quotation is not a representation
by the Fund as to what an investment in the Fund will actually yield for any
given period.
 
    The yield for the 30 days ended April 30, 1998 was 4.82% (4.77% without the
management fee waiver), 4.52% and 3.31% for Class A shares of the High Income
Series, Insured Series and Intermediate Series, respectively. The yield for the
30 days ended April 30, 1998 was 4.57% (4.52% without the management fee
waiver), 4.25% and 3.01% for Class B shares of the High Income Series, Insured
Series and Intermediate Series, respectively. The yield for the 30 days ended
April 30, 1998 was 4.32% (4.27% without the management fee waiver), 4.00% and
2.76% for Class C shares of the High Income Series, Insured Series and
Intermediate Series, respectively. The yield for the 30 days ended April 30,
1998 was 5.08% (5.03% without the management fee waiver), 4.76% and 3.51% for
Class Z shares of the High Income Series, Insured Series and Intermediate
Series, respectively.
 
    Each Series may also calculate the tax equivalent yield over a 30-day
period. The tax equivalent yield will be determined by first computing the yield
as discussed above. The Series will then determine what portion of that yield is
attributable to securities, the income of which is exempt for federal income tax
purposes. This portion of the yield will then be divided by one minus 39.6% (the
assumed maximum tax rate for individual taxpayers not subject to alternative
minimum tax) and then added to the portion of the yield that is attributable to
other securities. For the 30 days ended April 30, 1998, the tax equivalent yield
for the Class A shares of the High Income Series, Insured Series and
Intermediate Series was 7.98% (7.90% without the management fee waiver), 7.48%
and 5.48%, respectively. For the 30 days ended April 30, 1998, the tax
equivalent yield for the Class B shares of the High Income Series, Insured
Series and Intermediate Series was 7.57% (7.48% without the management fee
waiver), 7.04% and 4.98%, respectively. For the 30 days ended April 30, 1998,
the tax equivalent yield for the Class C shares of the High Income Series,
Insured Series and Intermediate Series was 7.15% (7.07% without the management
fee waiver), 6.62% and 4.57%, respectively. For the 30 days ended April 30,
1998, the tax equivalent yield for the Class Z shares of the High Income Series,
Insured Series and Intermediate Series was 8.41% (8.33% without the management
fee waiver), 7.88% and 5.81%, respectively.

    AVERAGE ANNUAL TOTAL RETURN. Each Series may from time to time advertise its
average annual total return. Average annual total return is determined
separately for Class A, Class B, Class C and Class Z shares. See "How the Fund
Calculates Performance" in the Prospectus.
 
    Average annual total return is computed according to the following formula:
 
                         P(1+T) to the power of n = ERV
Where: P = a hypothetical initial payment of $1000.
       T = average annual total return.
       n = number of years.
       ERV = Ending Redeemable Value at the end of the 1, 5 or 10 year periods
             (or fractional portion thereof) of a hypothetical $1000 payment
             made at the beginning of the 1, 5 or 10 year periods.
 
    Average annual total return takes into account any applicable initial or
contingent deferred sales charges but does not take into account any federal or
state income taxes that may be payable upon redemption.
 
    The average annual total return and subsidy/waiver adjusted average annual
total return from the inception of the Class A shares (January 22, 1990) and for
the one year and five year periods ended April 30, 1998 were as follows:

    AGGREGATE TOTAL RETURN. Each Series may also advertise its aggregate total
return. Aggregate annual total return is determined separately for Class A,
Class B, Class C and Class Z shares. See "How the Fund Calculates Performance"
in the Prospectus.
 
    Aggregate total return represents the cumulative change in the value of an
investment in a Series and is computed according to the following formula:
 
                                    ERV - P
                                    -------
                                       P
Where: P = a hypothetical initial payment of $1000.
       ERV = Ending Redeemable Value at the end of the 1, 5 or 10 year periods
             (or fractional portion thereof) of a hypothetical $1000 payment
             made at the beginning of the 1, 5 or 10 year periods.
 
    Aggregate total return does not take into account any federal or state
income taxes that may be payable upon redemption or any applicable initial or
contingent deferred sales charge.

return from the inception of the Class A shares (January 22, 1990) and for the
one year and five year periods ended April 30, 1998 were as follows:

                        ORGANIZATION AND CAPITALIZATION
 
    The Fund is a Massachusetts business trust established under a Declaration
of Trust dated November 3, 1986. The Declaration of Trust and the By-Laws of the
Fund are designed to make the Fund similar in certain respects to a
Massachusetts business corporation. The principal distinction between the two
forms relates to shareholder liability. Under Massachusetts law, shareholders of
a business trust may, in certain circumstances, be held personally liable as
partners for the obligations of the
 
                                      B-31
<PAGE>
fund, which is not the case with a corporation. The Declaration of Trust of the
Fund provides that shareholders shall not be subject to any personal liability
for the acts or obligations of the Fund and that every written obligation,
contract, instrument or undertaking made by the Fund shall contain a provision
to the effect that the shareholders are not individually bound thereunder.
 
    Massachusetts counsel for the Fund has advised the Fund that no personal
liability with respect to contract obligations will attach to the shareholders
under any undertaking containing such a provision when adequate notice of the
provision is given, except possibly in a few jurisdictions. With respect to all
types of claims in the latter jurisdictions and with respect to tort claims,
contract claims where the provision referred to is omitted from the undertaking,
claims for taxes and certain statutory liabilities, shareholders may be held
personally liable to the extent that claims are not satisfied by the Fund.
However, upon payment of any such liability, shareholders will be entitled to
reimbursement from the general assets of the appropriate Series of the Fund. The
Trustees intend to conduct the operations of the Fund in such a way so as to
avoid, to the extent possible, ultimate liability of the shareholders for
liabilities of the Fund.
 
    The Declaration of Trust further provides that no Trustee, officer, employee
or agent of the Fund is liable to the Fund or to a shareholder, nor is any
Trustee, officer, employee or agent liable to any third persons in connection
with the affairs of the Fund, except as this liability may arise from his or her
own bad faith, willful misfeasance, gross negligence, or reckless disregard of
his or her duties. It also provides that all third parties shall look solely to
the Fund property or the property of the appropriate Series of the Fund for
satisfaction of claims arising in connection with the affairs of the Fund or of
the particular Series of the Fund, respectively. With the exceptions stated, the
Declaration of Trust permits the Trustees to provide for the indemnification of
Trustees, officers, employees or agents of the Fund against all liability in
connection with the affairs of the Fund.
 
    The Fund does not intend to issue share certificates or hold annual meetings
of shareholders.
 
    The Fund and all Series thereof shall continue without limitation of time
subject to the provisions in the Declaration of Trust concerning termination by
action of the shareholders or by the Trustees by written notice to the
shareholders.
 
    The authorized capital of the Fund consists of an unlimited number of shares
of beneficial interest, $.01 par value, issued in three classes in separate
Series. Each Series of the Fund, for federal income tax and Massachusetts state
law purposes, will constitute a separate trust which will be governed by the
provisions of the Declaration of Trust. All shares of any Series issued and
outstanding will be fully paid and non-assessable by the Fund. Each share of
each Series represents an equal proportionate interest in that Series with each
other share of that Series. The assets of the Fund received for the issue or
sale of the shares of each Series and all income, earnings, profits and proceeds
thereof, subject only to the rights of creditors of that Series, are specially
allocated to the Series and constitute the underlying assets of the Series. The
underlying assets of each Series are segregated on the books of account and are
to be charged with the liabilities in respect to the Series and with a share of
the general liabilities of the Fund. Under no circumstances would the assets of
a Series be used to meet liabilities that are not otherwise properly chargeable
to it. Expenses with respect to any two or more Series are to be allocated in
proportion to the asset value of the respective Series except where allocations
of direct expenses can otherwise be fairly made. The officers of the Fund,
subject to the general supervision of the Trustees, have the power to determine
which liabilities are allocable to a given Series or which are general or
allocable to two or more Series. Upon redemption of shares of a Series of the
Fund, the shareholder will receive proceeds solely of the assets of such Series.
In the event of the dissolution or liquidation of the Fund, the holders of the
shares of any Series are entitled to receive as a class the underlying assets of
that Series available for distribution to shareholders.
 
    Shares of the Fund entitle their holders to one vote per share. Matters will
be acted upon by the vote of the shareholders of each class of each Series
separately, except to the extent otherwise provided in the Investment Company
Act. A change in the investment objective or investment restrictions for a
Series would be voted upon only by shareholders of the Series involved. In
addition, approval of any investment advisory agreement is a matter to be
determined separately by each Series. Approval by the shareholders of one Series
is effective as to that Series whether or not enough votes are received from the
shareholders of the other Series to approve the proposal as to those Series.
 
    Pursuant to the Declaration of Trust, the Trustees may authorize the
creation of additional series of shares (the proceeds of which would be invested
in separate, independently managed portfolios with distinct investment
objectives and policies and share purchase, redemption and net asset valuation
procedures) with such preferences, privileges, limitations and voting and
dividend rights as the Trustees may determine. All consideration received by the
Fund for shares of any additional series, and all assets in which such
consideration is invested, would belong to that series (subject only to the
rights of creditors of such series) and would be subject to the liabilities
related thereto.
 
    Pursuant to the Investment Company Act, shareholders of any additional
series of shares would normally have to approve the adoption of any advisory
contract relating to such series and of any changes in the investment objective
or investment restrictions related thereto. The Trustees have the power to alter
the number and the terms of office of the Trustees, and they may at any time
 
                                      B-32
<PAGE>
lengthen their own terms or make their terms of unlimited duration and appoint
their own successors, provided that always at least a majority of the Trustees
have been elected by the shareholders of the Fund. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees.

Notes to Financial Statements                    PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
Prudential Municipal Bond Fund (the 'Fund') is registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
The Fund was organized as an unincorporated business trust in Massachusetts on
November 3, 1986 and consists of three series: the High Yield Series, the
Insured Series and the Intermediate Series. Investment operations for Class A,
Class B, Class C and Class Z shares of each series commenced on January 22,
1990, September 17, 1987, August 1, 1994 and September 16, 1996, respectively.

The investment objectives of the series are as follows: (i) the objective of the
High Yield Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes, (ii) the objective of the Insured and
Intermediate Series is to provide the maximum amount of income that is eligible
for exclusion from federal income taxes consistent with the preservation of
capital. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic and political developments in a
specific state, region or industry.
- ------------------------------------------------------------
Note 1. Accounting Policies

Securities Valuation: Municipal securities (including commitments to purchase
such securities on a 'when-issued' basis) are valued on the basis of prices
provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Trustees.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost.

Financial Futures Contracts: A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of debt securities at a set
price for delivery on a future date. Upon entering into a financial futures
contract, the Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the 'initial margin.' Subsequent payments, known as 'variation
margin,' are made or received by the Fund each day, depending on the daily
fluctuations in the value of the underlying security. Such variation margin is
recorded for financial statement purposes on a daily basis as unrealized gain or
loss. When the contract expires or is closed, the gain or loss is realized and
is presented in the statement of operations as net realized gain (loss) on
financial futures contracts.

The Fund invests in financial futures contracts in order to hedge its existing
portfolio securities, or securities the Fund intends to purchase, against
fluctuations in value caused by changes in prevailing interest rates. Should
interest rates move unexpectedly, the Fund may not achieve the anticipated
benefits of the financial futures contracts and may realize a loss. The use of
futures transactions involves the risk of imperfect correlation in movements in
the price of futures contracts, interest rates and the underlying hedged assets.

Options: The Fund may either purchase or write options in order to hedge against
adverse market movements or fluctuations in value caused by changes in
prevailing interest rates with respect to securities which the Fund currently
owns or intends to purchase. When the Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Fund writes an option, it receives a premium and an amount equal to that
premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Fund realizes a gain or loss to the extent of the premium
received or paid. If an option is exercised, the premium received or paid is an
adjustment to the proceeds from the sale or the cost basis of the purchase in
determining whether the Fund has realized a gain or loss. The difference between
the premium and the amount received or paid on effecting a closing purchase or
sale transaction is also treated as a realized gain or loss. Gain or loss on
purchased options is included in net realized gain (loss) on investment
transactions.

The Fund, as writer of an option, has no control over whether the underlying
securities may be sold (called) or purchased (put). As a result, the Fund bears
the market risk of an unfavorable change in the price of the security underlying
the written option. The Fund, as purchaser of an option, bears the risk of the
potential inability of the counterparties to meet the terms of their contracts.

Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Interest income is recorded on the
accrual basis. The Fund amortizes premiums and accretes original issue discount
on portfolio securities as adjustments to interest income. Net investment
income, other than distribution fees, and realized and unrealized gains or
losses are allocated daily to each class of shares based upon the relative
proportion of net assets of each class at the beginning of the day. Expenses are
recorded on the accrual basis which may require the use of certain estimates by
management.

- --------------------------------------------------------------------------------
Federal Income Taxes: For federal income tax purposes, each series in the Fund
is treated as a separate tax paying entity. It is the intent of each series to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all net income to shareholders.
For this reason no federal income tax provision is required.

Dividends and Distributions: Dividends from net investment income are declared
daily and paid monthly. The Fund will distribute at least annually any net
capital gains. Dividends and distributions are recorded on the ex-dividend date.
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with Statement of Position 93-2:
Determination, Disclosure, and Financial Statement Presentation of Income,
Capital Gain, and Return of Capital Distributions by Investment Companies. For
the fiscal year ended April 30, 1998, the effect of applying this statement was
to increase undistributed net investment income and decrease accumulated net
realized gain by $171,122 for the Insured Series.

Custody Fee Credits: The Fund has an arrangement with its custodian bank,
whereby uninvested monies earn credits which reduce the fees charged by the
custodian.
- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'), doing business as Prudential Investments ('PI,'
the Subadviser or the investment adviser); PIC furnishes investment advisory
services in connection with the management of the Fund. PIFM pays for the cost
of the subadviser's services, the compensation of officers of the Fund,
occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears
all other costs and expenses.

The management fee paid PIFM is computed daily and payable monthly at an annual
rate of .50 of 1% of the average daily net assets of each series up to $1
billion and .45 of 1% of the average daily net assets of each series in excess
of $1 billion. PIFM has agreed to voluntarily waive a portion of each series'
management fee, which amounted to $535,931, $85,444 and $7,346 for the High
Yield Series, Insured Series and Intermediate Series, respectively. Such amounts
represented .05 of 1% of the average daily net assets or $.005 per share for the
High Yield Series and .02 of 1% of the average daily net assets or $.002 per
share for the Insured Series and Intermediate Series. Effective September 1,
1997, PIFM eliminated its management fee waiver for the Insured Series and
Intermediate Series.

The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund. The Fund compensates PSI for distributing and
servicing the Fund's Class A, Class B and Class C shares, pursuant to plans of
distribution (the 'Class A, B and C Plans'), regardless of expenses actually
incurred by PSI. The distribution fees are accrued daily and payable monthly. No
distribution or service fees are paid to PSI as distributor of the Class Z
shares of the Fund. Effective July 1, 1998, Prudential Investment Management
Services LLC will become the distributor of the Fund and will serve the Fund
under the same terms and conditions as under the arrangement with PSI.

Pursuant to the Class A, B and C Plans, the Fund compensates PSI for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1%, of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .10 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively,
for the year ended April 30, 1998.

PSI has advised the Fund that it received approximately $529,300 ($493,600-High
Yield Series; $30,400-Insured Series; $5,300-Intermediate Series) in front-end
sales charges resulting from sales of Class A shares during the year ended April
30, 1998. From these fees, PSI paid such sales charges to affiliated
broker-dealers which in turn paid commissions to salespersons and incurred other
distribution costs.

PSI has advised the Fund that for the year ended April 30, 1998, it received
approximately $1,320,700 ($866,900-High Yield Series; $388,200-Insured Series;
$65,600-Intermediate Series) in contingent deferred sales charges imposed upon
certain redemptions by Class B and C shareholders.

PSI, PIC and PIFM are indirect, wholly owned subsidiaries of The Prudential
Insurance Company of America.

The Fund, along with other affiliated registered investment companies (the
'Funds'), has a credit agreement (the 'Agreement') with an unaffiliated lender.
The maximum commitment under the Agreement is $200,000,000. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative

source of funding for capital share redemptions. The Fund has not borrowed any
amounts pursuant to the Agreement during the year ended April 30, 1998. The

Note 5. Capital

Each series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3.0%. Class B shares are sold
with a contingent deferred sales charge which declines from 5% to zero depending
on the period of time the shares are held. Class C shares are sold with a
contingent deferred sales charge of 1% during the first year. Class B shares
automatically convert to Class A shares on a quarterly basis approximately seven
years after purchase. A special exchange privilege is also available for
shareholders who qualify to purchase Class A shares at net asset value. Class Z
shares are not subject to any sales or redemption charge and are offered
exclusively for sale to a limited group of investors.

Report of Independent Accountants                PRUDENTIAL MUNICIPAL BOND FUND
- --------------------------------------------------------------------------------
To the Shareholders and Trustees of
Prudential Municipal Bond Fund

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of High Yield Series, Insured Series
and Intermediate Series (constituting Prudential Municipal Bond Fund, hereafter
referred to as the 'Fund') at April 30, 1998, the results of each of their
operations for the year then ended and the changes in each of their net assets
and the financial highlights for each of the two years in the period then ended,
in conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at April 30, 1998 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above. The accompanying financial
highlights for each of the three years in the period ended April 30, 1996 were
audited by other independent accountants, whose opinion dated June 13, 1996 was
unqualified.

                   APPENDIX I--GENERAL INVESTMENT INFORMATION
 
    The following terms are used in mutual fund investing.
 
ASSET ALLOCATION
 
    Asset allocation is a technique for reducing risk, providing balance. Asset
allocation among different types of securities within an overall investment
portfolio helps to reduce risk and to potentially provide stable returns, while
enabling investors to work toward their financial goal(s). Asset allocation is
also a strategy to gain exposure to better performing asset classes while
maintaining investment in other asset classes.
 
DIVERSIFICATION
 
    Diversification is a time-honored technique for reducing risk, providing
"balance" to an overall portfolio and potentially achieving more stable returns.
Owning a portfolio of securities mitigates the individual risks (and returns) of
any one security. Additionally, diversification among types of securities
reduces the risks (and general returns) of any one type of security.
 
DURATION
 
    Debt securities have varying levels of sensitivity to interest rates. As
interest rates fluctuate, the value of a bond (or a bond portfolio) will
increase or decrease. Longer term bonds are generally more sensitive to changes
in interest rates. When interest rates fall, bond prices generally rise.
Conversely, when interest rates rise, bond prices generally fall.
 
    Duration is an approximation of the price sensitivity of a bond (or a bond
portfolio) to interest rate changes. It measures the weighted average maturity
of a bond's (or a bond portfolio's) cash flows, I.E., principal and interest
payments. Duration is expressed as a measure of time in years--the longer the
duration of a bond (or a bond portfolio), the greater the impact of interest
rate changes on the bond's (or the bond portfolio's) price. Duration differs
from effective maturity in that duration takes into account call provisions,
coupon rates and other factors. Duration measures interest rate risk only and
not other risks, such as credit risk and, in the case of non-U.S. dollar
denominated securities, currency risk. Effective maturity measures the final
maturity dates of a bond (or a bond portfolio).
 
MARKET TIMING
 
    Market timing--buying securities when prices are low and selling them when
prices are relatively higher--may not work for many investors because it is
impossible to predict with certainty how the price of a security will fluctuate.
However, owning a security for a long period of time may help investors offset
short-term price volatility and realize positive returns.
 
POWER OF COMPOUNDING
 
    Over time, the compounding of returns can significantly impact investment
returns. Compounding is the effect of continuous investment on long-term
investment results, by which the proceeds of capital appreciation (and income
distributions, if elected) are reinvested to contribute to the overall growth of
assets. The long-term investment results of compounding may be greater than that
of an equivalent initial investment in which the proceeds of capital
appreciation and income distributions are taken in cash.
 
STANDARD DEVIATION
 
    Standard deviation is an absolute (non-relative) measure of volatility
which, for a mutual fund, depicts how widely the returns varied over a certain
period of time. When a fund has a high standard deviation, its range of
performance has been very wide, implying greater volatility potential. Standard
deviation is only one of several measures of a fund's volatility.

                    APPENDIX II--HISTORICAL PERFORMANCE DATA
 
    The historical performance data contained in this Appendix relies on data
obtained from statistical services, reports and other services believed by the
Manager to be reliable. The information has not been independently verified by
the Manager.
 
    This chart shows the long-term performance of various asset classes and the
rate of inflation.

performance of any asset class of any Prudential Mutual Fund.
 
Generally, stock returns are due to capital appreciation and reinvesting any
gains. Bond returns are due mainly to reinvesting interest. Also, stock prices
are usually more volatile than bond prices over the long-term.
 
Small stock returns for 1926-1980 are those of stocks comprising the 5th
quintile of the New York Stock Exchange. Thereafter, returns are those of the
Dimensional Fund Advisors (DFA) Small Company Fund. Common stock returns are
based on the S&P Composite Index, a market-weighted, unmanaged index of 500
stocks (currently) in a variety of industries. It is often used as a broad
measure of stock market performance.
 
Long-term government bond returns are represented by a portfolio that contains
only one bond with a maturity of roughly 20 years. At the beginning of each year
a new bond with a then-current coupon replaces the old bond. Treasury bill
returns are for a one-month bill. Treasuries are guaranteed by the government as
to the timely payment of principal and interest; equities are not. Inflation is
measured by the consumer price index (CPI).
 
Impact of Inflation. The "real" rate of investment return is that which exceeds
the rate of inflation, the percentage change in the value of consumer goods and
the general cost of living. A common goal of long-term investors is to outpace
the erosive impact of inflation on investment returns.

    Set forth below is historical performance data relating to various sectors
of the fixed-income securities markets. The chart shows the historical total
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds,
U.S. high yield bonds and world government bonds on an annual basis from 1987
through 1997. The total returns of the indices include accrued interest, plus
the price changes (gains or losses) of the underlying securities during the
period mentioned. The data is provided to illustrate the varying historical
total returns and investors should not consider this performance data as an
indication of the future performance of the Fund or of any sector in which the
Fund invests.
 
    All information relies on data obtained from statistical services, reports
and other services believed by the Manager to be reliable. Such information has
not been verified. The figures do not reflect the operating expenses and fees of
a mutual fund. See "Fund Expenses" in the Prospectus. The net effect of the
deduction of the operating expenses of a mutual fund on these historical total
returns, including the compounded effect over time, could be substantial.

     EQUITY FUNDS. FORBES magazine listed Prudential Equity Fund among twenty
mutual funds on its Honor Roll in its mutual fund issue of August 28, 1995.
Honorees are chosen annually among mutual funds (excluding sector funds) which
are open to new investors and have had the same management for at least five
years. Forbes considers, among other criteria, the total return of a mutual fund
in both bull and bear markets as well as a fund's risk profile. Prudential
Equity Fund is managed with a "value" investment style by PIC. In 1995,
Prudential Securities introduced Prudential Jennison Fund, a growth-style equity
fund managed by Jennison Associates Capital Corp., a premier institutional
equity manager and a subsidiary of Prudential.
 
    HIGH YIELD FUNDS. Investing in high yield bonds is a complex and research
intensive pursuit. A separate team of high yield bond analysts monitor
approximately 200 issues held in the Prudential High Yield Fund (currently the
largest fund of its kind in the country) along with 100 or so other high yield
bonds, which may be considered for purchase.(3) Non-investment grade bonds, also
known as junk bonds or high yield bonds, are subject to a greater risk of loss
of principal and interest including default risk than higher-rated bonds.
Prudential high yield portfolio managers and analysts meet face-to-face with
almost every bond issuer in the High Yield Fund's portfolio annually, and have
additional telephone contact throughout the year.
 
    Prudential's portfolio managers are supported by a large and sophisticated
research organization. Fourteen investment grade bond analysts monitor the
financial viability of approximately 1,750 different bond issuers in the
investment grade corporate and municipal bond markets--from IBM to small
municipalities, such as Rockaway Township, New Jersey. These analysts consider
among other things sinking fund provisions and interest coverage ratios.
 
    Prudential's portfolio managers and analysts receive research services from
almost 200 brokers and market service vendors. They also receive nearly 100
trade publications and newspapers--from PULP AND PAPER FORECASTER to WOMEN'S
WEAR DAILY--to keep them informed of the industries they follow.
 
    Prudential Mutual Funds' traders scan over 100 computer monitors to collect
detailed information on which to trade. From natural gas prices in the Rocky
Mountains to the results of local municipal elections, a Prudential portfolio
manager or trader is able to monitor it if it's important to a Prudential mutual
fund.
 
    Prudential Mutual Funds trade approximately $31 billion in U.S. and foreign
government securities a year. PIC seeks information from government policy
makers. In 1995, Prudential's portfolio managers met with several senior U.S.
and foreign government officials, on issues ranging from economic conditions in
foreign countries to the viability of index-linked securities in the United
States.
 
    Prudential Mutual Funds' portfolio managers and analysts met with over 1,200
companies in 1995, often with the Chief Executive Officer (CEO) or Chief
Financial Officer (CFO). They also attended over 250 industry conferences.
 
    Prudential Mutual Fund global equity managers conducted many of their visits
overseas, often holding private meetings with a company in a foreign language
(our global equity managers speak 7 different languages, including Mandarin
Chinese).
 
    TRADING DATA.(4) On an average day, Prudential Mutual Funds' U.S. and
foreign equity trading desks traded $77 million in securities representing over
3.8 million shares with nearly 200 different firms. Prudential Mutual Funds'
bond trading desks traded $157 million in government and corporate bonds on an
average day. That represents more in daily trading than most bond funds tracked
by Lipper even have in assets.(5) Prudential Mutual Funds' money market desk
traded $3.2 billion in money market securities on an average day, or over $800
billion a year. They made a trade every 3 minutes of every trading day. In 1994,
the Prudential Mutual Funds effected more than 40,000 trades in money market
securities and held on average $20 billion of money market securities.(6)
 
    Based on complex-wide data, on an average day, over 7,250 shareholders
telephoned Prudential Mutual Fund Services, Inc., the Transfer Agent of the
Prudential Mutual Funds, on the Prudential Mutual Funds' toll-free number. On an
annual basis, that represents approximately 1.8 million telephone calls
answered.
